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) = (-1, 5) and (x2, y2) = (2, -1).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(-2)x + (3)
