What are the coordinates for tree A?

You need to give the question in full.
Ok. Solve y= -2/3x-12
You already have an equation for y in terms of x. To "solve" it, you need to know what x is.

What does "tree A" have to do with an equation?
Disregard the first question and solve the equation.
y= -2/3x -12 is a "solution"

If you want x in terms of y, do the algebra.

(2/3)x = -12 -y

x = -18 -(3/2)y
