Rewrite this equation in slope intercept form. 00:30. write the following inequality in slope-intercept form. Does the answer help you? If x is equal to 0, y is going to be equal to negative 4, you can just substitute that in the graph. And remember it is just below the line as you count going up. In 1982, Robert "Bob" Moses (who had been providing additional math instruction to his daughter) joined, Mary Lou Mehrling, his daughter's eighth grade teacher, to help several students with the study of algebra. Plot the point (8, 5 8/9) which is just below of (5, 6). Create an account to get free access.
That's the point 0, negative 4. So x is equal to negative 2 is right there, negative 1, negative 2, and x is just always going to be equal to negative 2 in both directions. B is simply where the line will cross the y-axis when this line is graphed. Provide step-by-step explanations. Learn to convert equations like 4x + 2y = -8 into slope-intercept form. The equation y=5/8x+8/9 is is slope y-intercept form. Y is just going to stay at negative 4. Enjoy live Q&A or pic answer.
Could anybody please tell me how you graph a fractional number, like y=5/8x+8/9(6 votes). And the answer is you won't be able to because you this can't be put into slope-intercept form, but we can simplify it. You have to divide every term by 2. The other method you can use is to plot the y-intercept. How do i find the slope intercept form if the equation is written differently? Want to join the conversation? If I go over 2, I'm going to have to go down 4. Cancel the common factor.
If you choose 0 for x then y=5/8 * 0 + 8/9 = 8/9 so your first point is (0, 8/9). Now we're almost at slope-intercept form. Then you made a line at -2x. Do my best to draw it, that's a decent job. And then we are left with y is equal to negative 4 divided by 2 is negative 2x.
We're asked to convert these linear equations into slope-intercept form and then graph them on a single coordinate plane. So you might say hey, Sal, that doesn't look like this form, slope-intercept form, but it is. Why did he subtract 4? So the y intercept is at (0, 8/9). We have our coordinate plane over here. And then draw a line through the two points. We just have to get rid of this 2, and the best way to do that that I can think of is divide both sides of this equation by 2. Shouldnt he divide by 4? You can go up to more than five. The y intercept is (0, -7. In y=mx+b must b be a whole number(4 votes).
Also, if y= mx +b, shouldn't the slope in y = -2x - 4 be -2? So this line is going to look like this. In order to eliminate the coefficient (2) on Y. That's the y-intercept for line A. The graph has no y-intercepts if c is nonzero, and all real numbers for its y-intercepts if c is zero.
Crop a question and search for answer. So you divide both sides of this equation by 4. On line A why did he divide all terms by 2? Are there any possibility that a linear equation can't convert into slope intercept form? So this is line A, let me graph it right now. Now let's do this last character, 2y is equal to negative eight. The slope is 5/8, so from your y-intercept point, count right 8 and then go up 5. So we divide the left-hand side by 2 and then divide the right-hand side by 2. How did he get (0, -4) from y= -2x- 4? Enter your parent or guardian's email address: Already have an account?

So let's start with line A, so start with a line A. All right, let's do line B. Subtract from both sides of the inequality. Moses, who had taught secondary school mathematics in New York City and Tanzania, decided that an appropriate goal for those students was to have enough skills in algebra to qualify for honors math and science courses in high school. 5x - 5y is greater than or equal to 70. Let me just do that.
So, if b=1/2 then the line will cross the y axis between the 0 and the 1. Solved by verified expert. We can rewrite this as y is equal to 0x minus 4, where the y-intercept is negative 4 and the slope is 0. If I go back 2, I'm going to go up 4. Created by Sal Khan and Monterey Institute for Technology and Education.
Check the full answer on App Gauthmath. It also highlighted a serious problem: Most students in the Open Program were expected not to do well in mathematics. Try Numerade free for 7 days. This exceptional type of line is a vertical line with undefined slope. And you get x is equal to negative 2.
The left hand side of the equation, these two 4x's cancel out, and I'm just left with 2y is equal to. Back 2 and then up 4. A is a constant term. At time3:30you said that you can't make it into slope interval form. Ask a live tutor for help now. Plot the two points, and draw a line through the two point you plotted. The slope intercept form of a linear equation has the following form where the equation is solved for y in terms of x: y = a + bx. And this is the x-axis, that's the y-axis, I forgot to label them. Still have questions? Gauthmath helper for Chrome. Have a blessed, wonderful day! So then we are done. So line A, it's in standard form right now, it's 4x plus 2y is equal to negative 8.
His success in producing the first students from the Open Program of the Martin Luther King School who passed the city-wide algebra examination and qualified for ninth grade honors geometry was a testament to his skill as a teacher. So if I go over one in the positive direction, I have to go down 2, that's what a negative slope's going to do, negative 2 slope. We can divide both sides of this equation by 2, and we get y is equal to negative 4. If you choose 8 for x then y = 5/8 * 8 + 8/9 = 5 + 8/9 = 5 8/9. The first thing I'd like to do is get rid of this 4x from the left-hand side, and the best way to do that is to subtract 4x from both sides of this equation.
