15. Quadrilateral ABCD is transformed on a coordinate plane to obtain its congruent image Quadrilateral
A'B'C'D'. Which of the following statements could be
true?

the image of (6, 9) under a dilation is (4, 6). the scale factor is

i don't have the answer rn but go to math papa. it shows the steps and the answer. hope this : )

step-by-step explanation:

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)
