Mixed Problems on Systems of Equations

The graphical solution of a system of two linear equations can be described as:

The point of intersection of two lines.

A

Any point that is at an equal distance from two lines.

B

The angle between two lines at their point of intersection.

C

The distance between the $y$`y`-intercepts of two lines.

D

The point of intersection of two lines.

A
