Part 1: Find the slope of the hill.

Slope (m) = change in y over change in x.

Part 2: Now find the equation using the point slope formula.

Point Slope Formula: y – y1 = m (x – x1)

Part 3: Give an example of an equation for a line parallel to your answer from Part 2.

Part 4: Give an example of an equation for a line perpendicular to your answer from Part 2.
