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?

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