slope of AB :  (0,1)(-2,5) slope = (5-1) / (-2 - 0) = 4/-2 = -2/1 a perpendicular line will have a negative reciprocal slope.....all that means is " flip " the slope and change the sign. So we need a slope of 1/2(or 0.5) y = mx + b slope(m) = 0.5 (7,6)...x = 7 and y = 6 now we sub and find b, the y int 6 = 0.5(7) + b 6 = 3.5 + b 6 - 3.5 = b 2.5 = b so ur perpendicular line is : y = 0.5x + 2.5
