Answer:y=-2+3
Step-by-step explanation:I THINK
Step 1: Calculating Slope (m).m = y2-y1x2-x1m = (-19)-(19)(11)-(-8)m = -19-1911+8m = -3819m = -2Now putting value of m in equation (i)y = -2x + b -----(ii)Step 2: Calculating Y-intercept (b).Lets choose the first point, (-8,19) for calculating y-intercept:y = mx + b19 = -2(-8) + b19 = 16 + b3 = bb = 3Now putting value of b in equation (ii)y = -2x + 3
