Systems of Equations

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

• yes

• no

The solution (x, y) to a system of equations is the point where they...? 

• Run off the graph
• Don't touch
• Intersect
• Exist

What is the solution to the system?

• (0, 3)
• (1, -1)
• (-3, 1)
• (1, 3)

Solve the system:

3x - y = 7

and 2x + y = 3

• (-1,2)

• (5,4)

• (4,5)

• (2,-1)

• (2,5)

Solve the system of equations

y = 2x + 1 and y = 4x - 1

• (1,3)

• (-1,-3)

• (-1,3)

• (1,-3)
