Point C (4.2) divides the line segment joining points A (2.-1) and (x. y) such that AC:C8=3:1. What are the coordinates of point B? (10, 11) (11, 10)
(3, 14/3)
(14/3, 3)

step-by-step explanation:

compare

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

answer: the answer is e
