Solve by graphing the following lines on the graphs provided.
Graph both lines and determine the point of intersection.
1. y = -1x + 5
2. X – 2y = 2
y = 1x - 3
3x + y = 6
3. y 
II.
III.

x  2 and
3
1x – 3y = 6
Use substitution to solve each system of equations. Check answers.
Show all work . Answers can be integers only, including 0.
4.
y = 2x –7
5. Y = 4x
x + y =11
x + y =5
Use elimination to solve each system of equation.
Show all work and check answers.
6. 2x – y = 5
7. 3x – y = 11
8. y + x = 20
2x + y =3
