Question

Points D, C, B, and A are collinear.What is the slope of DC in simplest form?3BDSlope of DC = 0)=

Answer 1

To answer this question we will use the following formula for the slope of a line:

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

Since A, B, C, and D are collinear then:

`\text{slope of }\bar{\text{DC}}\text{=slope of }\bar{\text{AB}}\text{.}`

Now, from the given diagram, we get that, for AB:

`\begin{gathered} \text{rise}=3, \\ \text{run}=4. \end{gathered}`

Therefore:

`\text{slope of }\bar{\text{AB}}\text{=}(3)/(4)\text{.}`

Answer:

`(3)/(4)\text{.}`
