Steps:
1) Draw the circle and mark the center (A) and the given point (B)
2) Draw a line that passes through the center (A) and the given poiint (B).
3) Draw a perpendicular line to the segment AB.
The last line drawn is tangent to the circle at the given point.
The straight line graph is the one that shows a direct, proportional relationship.
1: 144 because
4 * 15 = 60 ft total height = 720 in total height
5: 720 = 1: 144
