Question

2. A ladder rises 20 feet for every horizontal change of 4 feet. What is the slope of the ladder?A. O 5C. O 20D.OChoose

Answer 1

The slope is defined as rise/run - in other words, for every step you take horizontally, how many steps you should take vertically to get to a point on the same line.

In our case, the ladder rises 20 feet for every horizontal change of 4 feet; therefore, the slope is

`\frac{\text{rise}}{\text{run}}=(20ft)/(4ft)`

dividing 30 ft by 4 ft gives 5; therefore,

`\frac{\text{rise}}{\text{run}}=5.`

Hence, the correct answer to choose is A. 5.
