Solving Systems of Nonlinear Equations by Graphing

If a nonlinear system contains a linear function that never touches the quadratic function, that system has...

• 2 solutions

• 1 solution

• No solutions

• Infinite solutions

Determine if the point (2,0) is a solution to the following system:

y=2x - 4

y=x² - 4

• Yes, because it works in one equation.

• Yes, because it works in the both equations.

• No, because it works in neither equation.

• No, because it works in only one equation.

Determine if the point (-1, -2) is a solution to the following system:

-4x² + 5y² + 2x - 63y + 108 = 0

x - 2y = -3

• Yes, because it works in one equation.

• Yes, because it works in the both equations.

• No, because it works in neither equation.

• No, because it works in only one equation.

• A (-2,0) (2,0)

• B (-2,0) (1,-3)

• C (0,-2) (-3,1)
