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?

7x15y+9=0
**Subtract 9 from both sides
7x15y=9
**Subtract 7x from both sides
15y=7x9
**Divide both sides by 15
y=(7/15)x+(9/15) < equation isolate for y
