Option D is the correct answer.
Answer:
D. ∠B and ∠C are congruent.
Step-by-step explanation:
Since, ∠A and ∠B are supplementary.
Therefore,
∠A + ∠B = 180°.....(1)
Since, ∠A and ∠C are supplementary.
Therefore,
∠A + ∠C = 180°.....(2)
From equations (1) & (2)
∠A + ∠B = ∠A + ∠C
=> ∠B = ∠C
Hence, ∠B and ∠C are congruent.
The answer is
3x-4y=-24
y=mx+b
-4y=-3x-24
y=(3/4)x+(-24/-4)
y=(3/4)x+6
slope m=3/4
y =6
ok so here we go:
1)
or 
2 )
so the answer is (0, -4) or -4
3) y=

4) y=[tex]\frac{3}{2}x+1[tex] so the answer is (0, 1) or 1
Here are your points (-9,-8), (-6,-2), (-2,-6)
