Solve the system by graphing:

y = 6x - 4

y = -x + 3

Turn in your work:

An x/y table AND

Your graph

• (2, 1)

• (4, 5)

• (2, 4)

Graph both equations. What point do they intersect at?

y = x + 3

y = -x - 1

Turn in the following:

An x/y table

Your graph

• (1, 3)

• (-1, 0)

• (-2, 1)

• (3, -1)

What is the solution to this system?
