Question

Write an equation of a line perpendicular to line CD below in slope-intercept form that passes through the point (-1, 6).

Answer 1

Select one:
a. y = 0.5x - 5.5
b. y = -0.5x + 5.5
c. y = 2x + 13
d. y = -2x - 13

Answer 2

Answer 3

(1,1) x1 = 1 and y1 = 1
(3,5) x2 = 3 and y2 = 5
slope(m) = (y2 - y1) / (x2 - x1)
now we sub
slope = (5 - 1) / (3 - 1)
slope = 4/2
slope = 2

perpendicular slope has negative reciprocal slope. All that means is " flip " the slope and change the sign. So are new slope will be -1/2, because that is the negative reciprocal of 2.
-1/2 is the same as -.5

that pretty much just leaves one answer choice that will work and that is answer choice B
