State whether the given point is a solution to the system of equations.

What is the best way to determine whether a given point is a solution to a system of equations? If you are asked if a point is a solution to an equation, we replace the variables with the given values and see if the 2 sides of the equation are equal (so is a solution), or not equal (so not a solution). ... So, we test the point in both equations.  Where is the solution of a system of equations? The solution to a system of linear equations is the point which lies on both lines. In other words, the solution is the point where the two lines intersect
