Complete the explanation of whether the graph represents a proportional or a nonproportional relationship.

Non-proportional

Step-by-step explanation:

slope = (16-10) / (2-1) = 6

equation: 22 = 6*3 + 4

28 = 6*4 + 4

y = 6x + 4

proportional linear relation should be: y = mx    (no y intercept)

(-1,-0.5)

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)
