Plugging in a value of x lets you compute y, or vice versa. It is the equation of a striaght line.

What are you supposed to do with the equation? Turn it into an equation for y?

7x-15y+9=0

**Subtract 9 from both sides

7x-15y=-9

**Subtract 7x from both sides

-15y=-7x-9

**Divide both sides by -15

y=(7/15)x+(9/15) <--- equation isolate for y
