On graph paper, graph a line with slope  that goes through the point .  

  1. Find the equation of the line.

    Substitute in the known values for slope , and to find the -intercept of this line.

    Now solve this equation for .

  2. Is this line perpendicular to the line ? Explain how you know.

    The slope of a line (a) perpendicular to another line (b) is the opposite reciprocal of line (b)'s slope.
    Solve this equation for to find the slope and compare it to the slope of the line in part (a).
