Quiz on Solving Systems

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)

Determine how many solutions the system has.

(Hint: Both lines are graphed over each other)

• One Solution

• No solution

• Infinitely Many Solutions

• Two solutions

Which graph represents a system of equations with no solution?

• 
• 
• 
• None of the above

y = 2x + 9

x = -3

• (-3, -33)

• (-3, 8)

• (-3, 3)

• (3, -3)

Solve the following systems of equations using substitution:

y = 8

y = -4x + 4

• (8, -1)

• (-28, 8)

• (-1, 8)

• (8, -28)

• (6, 6)

• (6, 9)

• (9, 6)

• (9, 9)

Solve by elimination:
4x+9y=28
-4x-y=-28
