Suppose CDEF represents the wing you built as part of the reconstruction of a vintage airplane model overline CF is to be attached to the plane with overline CD closest to the propeller. You friend will build the second wing, QRST, congruent to CDEF, but needs instructions for how to place their wing exactly like you did. What are your instructions?

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)

b. 153 students do not participate in sports and seventy-five 12th graders were surveyed
