There are ten problems on the quiz.
Find the solution to the system by GRAPHING.
Find the slope and y-intercept for each linear
equation.
1.) y = x + 3
y = -x + 7

2.) x + 9y = 9
3x + 6y = 6
Use LINEAR COMBINATIONS to solve the linear
system.
4.)
5x
–
3y
=
7
3.) x + y = 6
x + 3y = 5
x – y = 12

Use Linear Combinations to solve
the linear system.
5.) 2x + 3y = 36 6.) 2x + y = 0
2x – y = 4
5x – 4y = 26
7.) -4x + 7y = -2
x = -y – 5
Use SUBSTITUTION to solve the linear system.
8.) 4x – y = 8 9.) x + 3y = 9
10.) 5x – y = -5
y = 2x
4x – 2y = -6
3x + 6y = -3
