• A
• B
• C
• D

The ELIMINATION method would be the best method to solve for which system of equations?

• 5x - 7y = 16 and 2x - 7y = 12
• 4x + 3y = -5 and 6x - 3y = 2
• x = 3y + 1 and 2x + y = 7
• 2x + 6y = 3 and 3x + 2y = -1

What is the solution to the system in the previous image? (x,y)

• (0, -2)
• (-2, 0)
• (2,0)
• (0,2)

When both EQUATIONS have the same slope, does the system have a solution?

• No!! No solution!!
• Yes! Infinite solutions!

Which side do you shade when graphing an inequality?

• The side that makes the inequality false
• The side that makes the inequality true!

Parallel Lines never intersect because...

• they have the same slopes.
• they have different slopes.
• they have the same y-intercept.
• they have different y-intercepts.

Match the following graph to the systems of equations

• y=−x+7 AND y=2x+1
• y=-2x+4 AND y=-2x+4
• y=2/3x+1 AND y=2/3x-2
