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) = (2, 5) and (x2, y2) = (5, 40).
Slope a is .
Intercept is found from equation a%2Ax%5B1%5D%2Bb+=+y%5B1%5D, or 11.6666666666667%2A2+%2Bb+=+-18.3333333333333. From that,
intercept b is b=y%5B1%5D-a%2Ax%5B1%5D, or b=5-11.6666666666667%2A2+=+-18.3333333333333.

y=(11.6666666666667)x + (-18.3333333333333)
