Answer:
C
A
H
F
Step-by-step explanation:
graph shows slope =2
2. slope is y2-y1 / x2-x1
(4-7)/(1-0)
-3
so A
3. slope is 28-18 / 4-2
10/2 = 5
so H
4. graph shows slope =1

11 and 12 would be the answer for your equation
Answer:
With points A, B and C a right triangle is formed.
Given that BC ⊥ CA, then m∠C = 90°.
The addition of the angles of a triangle is equal to 180°, therefore:
m∠A + m∠B + m∠C = 180°
Substituting with m∠C = 90°:
m∠A + m∠B + 90° = 180°
m∠A + m∠B = 180° - 90°
m∠A + m∠B = 90°
