8. Triangle PQR has vertices P(-2,6), Q(-2,-2), and R(4,-2). It is translated according to the rule (x, y) = (x + 2, y-1). What is the
y-value of Q'? Show your work.

0.02040816326

step-by-step explanation:

mean or average is 40.6

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)

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)
