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) = (-1, -1) and (x2, y2) = (9, 1).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(0.2)x + (-0.8)
