Systems of Equations Quick Check

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. 

Answer explanation

When you graph the same equation twice, both graphs overlap completely, meaning every point on the line is a solution. Therefore, you will have infinite solutions.

How many solutions?

• One solution

• No solutions

• Infinitely many solutions

Answer explanation

The equation has one unique solution, meaning there is exactly one value that satisfies it. This is why the correct answer is 'One solution'.
