  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
