Question

I'm very confuesed where to start this problem:

Graph −18x+9y=72

Answer 1

Plug in x=0 and plot the point, then plug in y = 0 and plot the point.

Answer 2

y=-2x+8

Explanation:

first you have to -18x on both sides because you want to get y by itself

9y=-18x+72

then divide 9 by both sides

9y/9=-18x+72/9.....-18/9=-2 and 72/9=8

y=-2x+8

-2x is your slope and 8 is your y intercept
