Indira is using a number line to add Negative 1 + (negative 3). She begins by showing –1 on the number line, as shown below. A number line going from negative 5 to positive 5. The area between negative 1 and 0 is highlighted. What is the sum of Negative 1 + (negative 3)? –4 –3 2 3

i think the answer is d im not sure

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)
