Determining Solutions to Systems of Equations by Graphing

Which ordered pair(s) is a solution to the given system?

• (5, -5)

• (0,0)

• (-5, -2)

• (3,-3)

You can solve systems using these methods:

• graphing, substitution, and elimination

• rearranging, substituting points, and plotting points

• graphing and determining the intersection

• Solving for y, then graphing

Solve the system of equations:

y = -6x + 5

-2x + y = 5

• (-3, -6)

• (-6, 3)

• (0, 5)

• (-3, 5)

Solve for x and y.

y = 2/3x - 2

y = -x + 3

• (0,3)

• (0,-3)

• (3,0)

• (-3,0)

Solve the system by graphing.

3x + y = 4

x - y = 4

Choose the 2 equations that are graphed and the solution to the system.

• (1, -2)

• (2, -1)

• (2, -2)

The sum of Mr. Micklow and Ms. Craft's age is 55.  The difference is 3.  
Solve:
x + y = 55
x - y = 3

• (26, 23)

• (26, 29)

• (29, 26)

• (29, 32)

Solve for x and y
3x + 2y = 16
7x + y = 19

• (-2,5)

• (-2,-5)

• (2,-5)

• (2,5)
