Step-by-step explanation

Three or more points are collinear if the slope of any two pairs of points is the same

From the question.

Thus, for line AB


\begin{gathered} \text{slope of AB is given by} \\ \text{slope AB=}(rise)/(run)=\frac{change\text{ in y}}{change\text{ in x}}=(3)/(1)=3 \end{gathered}

Similarly, the slope of DC will be equal to that of AB because they are collinear

Thus


\text{slope of DC=3}
