Graph the line .

  1. Sketch the line that is perpendicular to  that passes through the point .

    Use the slope and -intercept to graph the original line.

    What is the relationship between the slopes?

  2. Write the equation of the perpendicular line.

    With the new slope, write the equation in  form and solve for .

  3. Where do the lines intersect?

    Set the equations equal to each other to solve for . Then solve for .
