,

Since is a vertical line, the slope is undefined.

Undefined

The slope-intercept form is , where is the slope and is the y-intercept.

Using the slope-intercept form, the slope is .

Set up the system of equations to find any points of intersection.

The solution to the system of equations can be represented as a point.

Since the slopes are different, the lines will have exactly one intersection point.
