Equation: Y = mx + b First of all, we will solve for our M which is our slope. M = Yb - Ya / Xb - Xa M = 9 - (-3) / 2 - 0 M = 9 + 3 / 2 - 0 M = 12 / 2 M = 6
Now that we have our slope, we will be finding our y-intercept. Y = mx + b 9 = (6)(2) + b 9 = 12 + b = 9-12 = 12-12 + b (12 cancels out) = -3 = b
