Question

1) What is the slope (grade) of a road that rises 6 feet for every horizontal change of 600 feet?a) 1100b) 16d) seChoose

Answer 1

Let's conside the change in values in y axis with the increasing order of 600,1200,1800......

And the change in values in x axis with increasing order of 6,12,18,24.......

To find the slope, let'ss take

`\begin{gathered} x_1=6 \\ x_2=12 \\ y_1=600 \\ y_2=1200 \end{gathered}`

The formula to find the slope is,

`m=\frac{y_2-y_1}{x_2-x_1_{}}`

By substituting the values in the formula,

`\begin{gathered} m=(1200-600)/(12-6) \\ m=(600)/(6) \\ m=100 \end{gathered}`

Hence the value of slope, m is 100
