• (6, 5) and (2, 5)

• (2, 6)

• (6, 2)

• (5, 6) and (5, 2)

Determine the number of solutions to the given linear-quadratic system.

• 0 solutions
• 1 solution

• Nobody cares

Which of the following graphs correctly represents:

y=x²

y=-2x+1

• 
• 
• 
• 

Which of the following represents the first step in solving:

y = x² + 3x - 5

y = x + 3

• x² - 3x + 5 = x - 3

• x² + 3x - 5 = x + 3

• x² + 3x - 5 + x + 3 = 0

• x² + 3x - 5 = 0
