Toni participates in a 10-mile charity walk. For each mile she walks, a sponsor will donate $9 to the charity. The graph represents the function that models the amount of money the sponsor will donate given the number of miles, x, Toni
walks.

9 times 10 equal 90 $

Step-by-step explanation:

x=30

step-by-step explanation:

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)
