Write an equation in slope-intercept form for the line that passes through the given point and is perpendicular to the given line.(4, −2); y = 3

Answer 1

The given line (y = 3) is a horizontal line, so the perpendicular line is a vertical line, which is a line of constant x, with its slope undefined. Since (4,-2) is on the line, the equation is

x = 4

This line has no y-intercept.
