9-31.

Line m has intercepts and .

  1. Find the equation of line m.

    You are given the y-intercept. Calculate the slope and write the equation.

  2. Is the point also on line m? How do you know?

    Substitute the given point into the equation you wrote in part (a). Do you get a true statement?

  3. Write the equation of a line that is perpendicular to line m and passes through the point .

    The slope of the perpendicular line will be the opposite reciprocal of line m.
