Solution
Since they are collinear, that means they are on the straight line and thus have the same slope.
From the straight line graph, the line has a positive slope
Thus, from the graph
[tex]\begin{gathered} SlopeOfDC=\frac{\text{change in y}}{change\text{ in x}} \\ SlopeOfDC=\frac{5}{1} \\ SlopeOfDC=5 \end{gathered}[/tex]
Therefore,
[tex]SlopeOfDC=5[/tex]
