Find an equation of the line described below. Write the equation in​ slope-intercept form​ (solved for​ y), when possible. With undefined slope,through (7/8,-8)

Since the slope is undefined, the line is vertical and can be written as x = a, where a is the x-coordinate of any point on the line.

In this case, the line passes through (7/8, -8), so the equation of the line can be written as x = 7/8.
