Question

Points D, C, B, and A are collinear.What is the slope of DC in simplest form?2.A5BCSlope of DC =[?]=YD

Answer 1

Explanation: To calculate the slope we can use the following formula

$\text{slope}=\frac{\text{rise}}{\text{run}}$

Also, we can see that even DC has a larger length than BA the slope of the line does not change which means the slope for BA is the same for DC.

Once we know that, we have

$\begin{gathered} \text{slopeAB}=\frac{\text{rise}}{\text{run}} \\ \text{slopeAB}=\frac{5}{2} \\ \text{slopeAB}=slopeDC=\frac{5}{2} \end{gathered}$

Final answer: So the final answer is

$\text{Slope of DC= }\frac{5}{2}$
