The diameter of the circle is 8 cm, as
shown. the sum of the top two shaded
areas is the area of half the circle minus
the area of the triangle. the shaded
area below is a 60° sector of the circle.
find the sum of the three shaded areas.

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)

yes

step-by-step explanation:

they have to be opposite and reciprocal of eachother.

i don't even know how to read that, ill try to do it if you translate it into english.
