When graphing a system of two linear equations, what does the point of intersection of the two lines represent?

A point on only one of the lines

A student finds that the solution to a system of equations is $(4, 1)$. How can the student verify this solution graphically?

Graph both equations and check if they intersect at $(4, 1)$.

Graph one equation and check if it passes through $(4, 1)$.

Check if $(4, 1)$ is the y-intercept of both lines.

Confirm the slopes of the lines are $4$ and $1$.

His algebraic solution is incorrect.

The system has infinite solutions.
