Solved by pluggable solver: FIND EQUATION of straight line given 2 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) = (-2, 5) and (x2, y2) = (-6, -8).
Slope a is a+=+%28y%5B2%5D-y%5B1%5D%29%2F%28x%5B2%5D-x%5B1%5D%29+=+%28-8-5%29%2F%28-6--2%29+=+3.25.
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 3.25%2A-2+%2Bb+=+11.5. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=5-3.25%2A-2+=+11.5.

y=(3.25)x + (11.5)

Your graph:




so, a slope intercept form equation is y=3.25x+%2B11.5
