D.-4
I

D -4

Step-by-step explanation:

rise over run rise=-12 run= 3 - 12/3 simplified is -4

4

Step by step

you move 12 spots to get to 8 from -4 and 3 to get from -1 to 2 then you do 12/3

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

m∠a is 90°

m∠b is 40°
