Question

$x + y = 8$
​

Answer 1

Answer:

If you would like to find both the x and y intercepts, this form is already ideal: just set x to 0 and you have y = 8, so the y intercept is (0, 8), and set y to 0 and you have x = 8 meaning that the x intercept is (8, 0). Now you can plot the line, if you like.

To solve for y, you can convert your equation to slope-intercept form by subtracting x from both sides:

y = -x + 8

So there’s a slope of -1 and of course we already knew the y intercept was (0, 8).
