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{.}
