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

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.

2x - 7y = 28

-7y = - 2x + 28

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

y = 2/7x - 4
