Systems Review

Does the system have one, none or infinite solutions?
8x + 4y = 12
y = -2x + 3

• (0,3)
• (3,0)
• No solution(parallel lines)
• Infinitely many solutions

What is the solution to the system?

• (3, -1)
• (2, -6)
• No Solution 
• (6, -2)

Solve the system of equations by elimination.
-x + y = -13
-8x - 4y = -8 

• (5, 8)
• (5, -8)
• (-5, -18)
• (-5, 8)

Solve using substitution.

• (5, 4)
• (4, 5)

If a system of equations has no solution, what does the graph look like? 

• intersecting lines
• parallel lines
• skew lines
• intersecting lines

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)

What does the graph of a system with infinite solutions look like?

• The lines are parallel to one another.

• The lines cross one another at only one point.

• The lines are directly on top of one another (looks like one line)

What is the solution to the system of equations?

3x + 4y = -23

-x + 2y = -19

• No Solution

• Many Solutions

• (3, -8)

• (-7, 19)

Find the solution to the system of equations:
3x + 2y = 16
y = -7x + 19

• (-2,5)
• (-2,-5)
• (2,-5)
• (2,5)
