Question

Find the y-intercept of 2x - 7y =28

Answer 1

If you arrange this properly in the slope intercept form (y=mx+b) so just make it arranged in this format.
4x-7y=-28
Subtract 4x
-7y=-28-4x

Rearrange.
-7y=-4x-28
Divide by -7
y=4/7x+28
The number next to x is your slope and the other number is your y-intercept.

Answer 2

2x - 7y =28
-7y = -2x +28
-7y/-7 = -2x +28/-7
y = 2/7x -4
