The equations of linear system are .

For ease of graphing, rewrite the equation 1: in slope - intercept form.

Subtract x from each side.

.

The slope of is and its y - intercept is .

The slope of is and its y - intercept is 5.

The equations of graph in the same coordinate plane is

Observe the graph, the two lines are parallel because they have same slope but different y - intercepts.The parallel lines do not intersect, so the linear system has no solutions.

The linear system has no solutions.
