Solving Systems by Graphing
A system of equations is a set of two or more
equations containing two or more variables.
A solution of a system of equations is an
ordered pair that satisfies each equation
in the system.
Is the ordered pair a solution of the system?
{
x + 3y = 4
-x + y = 2
{ 3xx -- yy == 013
2
5
(-2, 2)
(5, 2)
I'm thinking of two numbers.
Their sum is 8 and their difference is 2.
What are the two numbers?

Find the solution to the system of equations by graphing.
{
y = 2x - 4
y = -12 x + 1
Choose your Problem:
Solve the system by graphing
Level A
{
y = 3x - 5
y=x-3
Level B
{
y=x+4
6x + 3y = 3
Level C
x-y = 1
5x - 4y = 0
