The equations of linear system are .
For ease of graphing, write each equation in slope - intercept form.
Rewrite equation 1: in slope - intercept form.
Subtract x from each side.
.
Rewrite equation 2: in slope - intercept form.
Add x to each side.
.
The equations of graph in the same coordinate plane is
Observe the graph, the lines appear to intersect at the point .
To check the ordered pair is a solution of linear system, substitute for x and 2 for y in each of the original equations.
Substitute for x and 2 for y in the equation 1: .
.
The above statement is true, so is a solution of equation 1.
Substitute for x and 2 for y in the equation 2: .
.
The above statement is true, so is a solution of equation 2.
Because is a solution of each equation, it is a solution of the linear system.
The solution of the linear system is .
