Answer:
E(-3,4) and F(2,9)
Step-by-step explanation:
If we plug in for x to see what we get for y:
(1,8):
y = 2(1)^2+ 3(1) - 5
y = 2 + 3 - 5
y = 0
This is wrong.
(-5,10):
y = 2(-5)^2 + 3(-5) -5
y = 50 - 15 - 5
y = 30
This is wrong.
(3,6):
y = 2(3)^2 + 3(3) - 5
y = 18 + 9 - 5
y = 22
This is wrong.
(-3, 4):
y = 2(-3)^2 + 3(-3) - 5
y = 18 - 9 - 5
y = 3
This is correct!
Lets check the last one...:
(2,9):
y = 2(2)^2 + 3(2) - 5
y = 8 + 6 - 5
y = 9
This is also correct!
So your right answers are:
E and F!
Hope this helps! :D
