If P is quadrupled (increased by a factor of 4), what is the effect on E?
a. E is unchanged
c. E is increased by a factor of 4
b. E is increased by a factor of 2
d. E is increased by a factor
of 16

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)

3

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
