Are these numbers linear or nonlinear? 1. 5, 10, 15, and 20
2. 13, 28, 43, and 58
3. 1, 3, 5, and 7
4. -2, -18, -50, and -98

1 is linear 4 is also linear,

Step-by-step explanation:

im not entierly sure

1/4 because there is 4 grades.

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)
