9-31.

Line has intercepts

Find the equation of line

.You are given the

-intercept. Calculate the slope and write the equation.Is the point

also on line ? How do you know?Substitute the given point into the equation you wrote in part (a). Do you get a true statement?

Write the equation of a line that is perpendicular to line

and passes through the point. The slope of the perpendicular line will be the opposite reciprocal of line

.
