System of Equations

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

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

If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines
• the same line 
• Intersecting lines

Solve the system of equations.
y = 4x+1
3x + 2y = 13

• (1, 5)
• (5, 1)
• (0.25, 2)
• ∅

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

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

Determine if (4, 1) is a solution for the system of equations.
y = -x + 5
y = 2x - 7

• yes
• no

Solve the following system
x + 9y = 8
-6x - 9y = -3

• (1,-1)
• (1,1)
• (-1,1)
• (-1,-1)

5x - 4y = =-16
x+ 2y = -6

• (-4,-1)
• (5,-1)
• (-5,-1)
• (4,1)

x = - 3
2x + 3y = 6

• (4,3)
• (-4,3)
• (-3,4)
• (3,-4)

2x - 3y = 6
7x - 3y = -9

• (-3,-4)
• (3,4)
• (-4,-3)
• (4,3)
