Ineed with identifying parallel and perpendicular lines from equations.

Let f(x) = 3 − x . find the average rate of change of f(x) from x = a to x = a + h and simplify your answer so that no single factor of h is left in the denominator.

The length of a rectangular piece of land is 92 yards more than three times its width. the perimeter is 760 yards. find its dimensions.

What is the difference between the equations of a vertical and a horizontal line?
