Solve the equations for y and state the slope and y-intercept:

. . .4x - 7y = 10
 
Hi Austinj

This is the way I would approach this question:

\(\displaystyle \large\\4x-7y=10\\
-7y=-4x+10\\
-y=-\frac{4x}{7}+\frac{10}{7}\)

Therefore we times it all by -1. That way y is positive!!

You should end up with

\(\displaystyle \large\\y=\frac{4x}{7}-\frac{10}{7}\)
