A system of linear equations contains two or more equations e.g.
y=0.5x+2 and y=x-2. The solution of such a system is the ordered
pair that is a solution to both equations. To solve a system of
linear equations graphically we graph both equations in the same
coordinate system. The solution to the system will be in the point
where the two lines intersect.
Graph the equations in a coordinate plane
The two lines intersect in (-3, -4) which is the solution to
this system of equations.
