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) = (-7, 0) and (x2, y2) = (0, 9).
Slope a is .
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 1.28571428571429%2A-7+%2Bb+=+9. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=0-1.28571428571429%2A-7+=+9.

y=(1.28571428571429)x + (9)

Your graph:
