The lateral surface area l of a cone varies jointly as the base radius r and the slant height l, and l =63π m2 when r = 3.5 m and l = 18 m. find r to the nearest tenth when l = 8πm2 and l = 5 m.

probability for j is 1/4

while

a is 1/6

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)
