Checking Solutions to Linear Equations

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

• Run off the graph

• Don't touch

• Intersect

• Exist

Solve the following system by checking each answer choice. Remember you must "plug in" the x-value and y-value from the point into BOTH equations.

y = 1/2x + 2

y = -3x + 9

• (2, 3)

• (-2, -3)

• (3, 2)

• (-3, 2)

Solve the following system by checking each answer choice. Remember you must "plug in" the x-value and y-value from the point into BOTH equations.

y = 2x + 1

y = 4x - 1

• (1,3)

• (-1,-3)

• (-1,3)

• (3,1)

Find the slope of the line.
