y = -2x + 3

• Two solutions
• One solution
• No solution
• Infinitely many solutions

Solve the system of equations by substitution.
y = 8x + 12
-5x +4y = 21

• (1, -4)
• (1, 20)
• (-1, 20)
• (-1, 4)

Buzz graphed the following two lines. One line has equation y=-6x+2. Which of the following is an equation of the other line?

• x+y=-3
• x+y=3
• 3x+3y=3
• -3x-3y=3

When you graph the exact same equation twice,

• you will have no solution. 
• you will have one solution.
• you will have infinite solutions. 
• you will graph a giraffe. 

How many solutions will this system have? 

• No solution
• One Solution
• I Don't Know
• Infinitely Many Solutions

Solve the system using Multiplication. 
2x + 3y = 12
5x - y = 13

• x = -3, y = -2
• x = 1.5, y = 2
• x = 6, y = 0
• x = 3, y = 2
