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) = (8, -3) and (x2, y2) = (-5, -2).
Slope a is .
Intercept is found from equation , or . From that,
intercept b is , or .

y=(-0.0769230769230769)x + (-2.38461538461538)

first find the slope:

slope = -1/13
Then use y=mx+b and substitute one set of points into the equation:
-3=(-1/13)(8)+b
-3=-8/13+b
-3+8/13=b
-31/13=b

so the equation is y=-1/13x+-31/13
