#### Understanding

Students understand that the solution to a system of two linear equations is the intersection of the graphical representation of the two equations.

### What to look for

Students make the connection between the \((x, y)\) pair that makes each equation true and the point of intersection of the two lines.

### Sample Assessment

Joe solved this linear system correctly.\(6x+3y=6\)

\(y=2x+2\)

These are the last two steps of his work

\(6x-6x+6=6\)

\(6=6\)

Which statements about this linear system must be true?

a. \(x\) must equal 6

b. \(y\) must equal 6

c. There is no solution to this system

d. There are infinitely many solutions to this system

Answer: d
