Answer:

Step-by-step explanation:
You are looking for the point of intersection of these two functions.
Substitution:
- This are now your formulas

- You are going to substitute x, so you can solve for y




- Now you are going to substitute y to find x



- Now lets check if it is correct

So it is true, making (-4 , -5) your point of intersection.
hope it helps
I'd go with the first option (2,-2.5) because the answers you get from solving the equation is
x = 9/5
y = -14/5
The x would round up to 2 and the y would round down to -2.5
57
2^2=4
4+4=8
6*8=48
48+9=57
