Slope and Right Triangles

Imagine a line follows the path of the hypotenuse in a right triangle. What is the slope of a down line with a height of 4 units and a base of 12 units?

• the slope is –0.33

• the slope is –3

• the slope is –4

• the slope is –0.25

The points (–5,5) and (0,0) create a connected right triangle with a height of 5 units and a base of 5 units. What is the slope of the line?

• the slope is 1

• the slope is –1

• the slope is –5

• the slope is 5

The two end points of (0,–2) and (4,–1) create a connected right triangle with a height of 1 unit and a base of 4 units. What is the slope?

• the slope is 4

• the slope is 0.25

• the slope is –4

• the slope is –0.25
