Write an equation in slopeintercept form for a line that passes through the given point and is perpendicular to the given line.
1. y=3;(4,2)
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)
