Question

Which system of equations is represented by the graph?

Answer 1

y = x2 − 5x − 3
6x − y = −27

y = x2 − 5x + 3
6x − y = 27

y = x2 + 5x + 3
6x + y = −27

y = x2 + 5x − 3
6x + y = 27

Answer 2

I'm pretty sure it's y=x^2+5x+3 because what I did was look at x=1 and notice that it is at (1,9) so if you let x=1 and y=9, then the equation would be 9=1^2+5(1)+3

Answer 3

I don't know about that other equations under the main equation.
