Algebra-1

To determine if the points (1, -1) and (-2, 8) are solutions to the given system of equations, we need to substitute the  and  values of each point into both equations and check if the equations are satisfied.

For the point (1, -1):

Equation 1:

Substitute  and  into the equation:

The point (1, -1) satisfies the first equation.

Equation 2:

Substitute  and  into the equation:

Since , the point (1, -1) does not satisfy the second equation.

So the point (1, -1) only satisfies one of the equations.

For the point (-2, 8):

Equation 1:
