choose an equation in slope-intercept form for the line that passes through (-8,1) and is perpendicular to the y=2x-17. select one: a. y= -(1/2)x - 3 b. y= -(1/2)x - 5 c. y= -2x - 4 d. y= -2x 1
y = 2x - 17....slope here is 2....perpendicular slope would be the negative reciprocal of 2...all that means is " flip " the slope and change the sign. So the perpendicular of 2, or 2/1, is -1/2.
y = mx + b slope(m) = -1/2 (-8,1)...x = -8 and y = 1 now we sub 1 = -1/2(-8) + b 1 = 4 + b 1 - 4 = b -3 = b
so ur perpendicular line is : y = -1/2x - 3....answer A
