Answer:
B) (20,8) , (30,13) , (40,18)
Step-by-step explanation:
To check: (20,8)
y = 1/2x - 2
8 = 1/2(20) - 2
8 = 10 - 2
8 = 8
This is true, which makes our point true.
To check: (30,13)
y = 1/2x - 2
13 = 1/2(30) - 2
13 = 15 - 2
13 = 13
This is true, which makes our point true.
To check: (40,18)
y = 1/2x - 2
18 = 1/2(40) - 2
18 = 20 - 2
18 = 18
This is true, which makes our point true.
Hope that helps!
