Answer:
B. 103°
Step-by-step explanation:
Supplementary angles add up to 180°, so we can find the measure of angle 2 by subtracting 77 from 180
180 - 77
= 103
So, m∠2 is 103°

Answer:
y=-2x-2
Step-by-step explanation:
Slope: -4-2/1-(-2)=-6/3=-2
Equation: y=-2x+b
Substitute: 2=-2(-2)+b
2=4+b
b=-2
Therefore, y=-2x-2
I hope this helped and have a good rest of your day!
