1. Explain each of the following problems in terms of the model of hot and cold cubes.
Your explanation should include a
statement of how the temperature changes
overall in each case.
a. 3 - (-2)
b. 5. (-4)

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)

x= 3^y
