Write an equation in slope-intercept form for a line that passes through the given point and is perpendicular to the given line.
The y = 3 line is parallel to the x axis so the perpendicular line you want is parallel to the y axis. That means x must be a constant in the equation for that line. Since it goes through the point (x = 4, y = -2), the equation is x = 4. (y can be anything, including -2)
What line is perpendicular to y=7/8-2
