5. Which is the best definition of joint variation? In joint variation there is a constant value for x and y.
In joint variation you can find the value of Z if you know the values of x and k.
Joint variation occurs when a single quantity is affected by two or more other quantities.
Joint variation occurs when the ratio between two quantities is constant.

nswer: a   y-axis

step-by-step explanation:

you'll just earn points here

step-by-step explanation:

i believe it's a.

i'm not sure on this one, most likely correct.

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)
