Intersection Solution

Give the solution to the system.

• (3,1)

• (1,3)

• (-1,3)

• No solution

When you graph the exact same equation twice,

• you will have no solution. 

• you will have one solution.

• you will have infinite solutions. 

• you will graph a giraffe. 

Graph using your calculator and then find the solution (intersection point).
