Question

y = x2 + 10x + 11 y = x2 + x − 7

Answer 1

Geometric figure: Straight Line

Slope = -1.636/2.000 = -0.818
x-intercept = -7/9 = -0.77778
y-intercept = -7/11 = -0.63636

Answer 3

Looks like a system of equations to me. Let's solve it:

y = x^2 + 10x + 11
y = x^2 + x - 7

Subtract the second equation from the first to get:

0 = 9x + 18
-18 = 9x
-18/9 = x
-2 = x

Plug the value of x back in to one of the original equations to find y
