Question

I'll send you pictures of the graph and questions:)Find the rise, run and rate

Answer 1

To find the rise (DISTANCE IN Y) of the triangle CDE you use the coordinates in y for the points E and D.

E (11,5) y=5

D (11,-7) y= -7

The rise is:

`\begin{gathered} rise_{}=y_E-y_D \\ =5-(-7) \\ =5+7=12 \end{gathered}`Then, the rise of the given traingle is 12

The run (distance in x) of the triangle CDE is:

C (-10,-7) x=-10

D (11,-7) x=11

`\begin{gathered} \text{run}=x_D-x_E \\ =11-(-10) \\ =11+10=21 \end{gathered}`Then, the run of the given triangle is 21

The rate is:

`\begin{gathered} \text{rate}=\frac{rise}{\text{run}} \\ \\ =(12)/(21)=(4)/(7) \end{gathered}`Then, the rate of the given triangle is 4/7
