(1,-5)(3,-17) slope = (-17 - (-5) / (3 - 1) = - 12/2 = - 6 y = mx + b slope(m) = -6 use either of ur points...(1,-5)...x = 1 and y = -5 now we sub and find b, the y int -5 = -6(1) + b -5 = -6 + b -5 + 6 = b 1 = b so ur equation is : y = -6x + 1....or 6x + y = 1

slope = (-17 +5)/(3 -1) = -12/2 = -6 y = mx + b -5 = -6(1) + b b = 1 equation y = -6x + 1 hope it helps
