Find an equation of the line described below. Write the equation in slope-intercept form (solved for y), when possible.
with undefined slope, through (1/2,-1)
Since the slope is undefined, the line must be vertical. In slope-intercept form, the equation will be of the form x = b, where b is a constant.
In this case, the line passes through the point (1/2, -1), and since it is vertical, the x-coordinate will always be 1/2. Therefore, the equation of the line is:
x = 1/2
