Solved by pluggable solver: Find the equation of line going through points
hahaWe are trying to find equation of form y=ax+b, where a is slope, and b is intercept, which passes through points (x1, y1) = (9, -2) and (x2, y2) = (12, 0).
Slope a is .
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 0.666666666666667%2A9+%2Bb+=+-8. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=-2-0.666666666666667%2A9+=+-8.

y=(0.666666666666667)x + (-8)

Your graph:

y=%282%2F3%29x-8
