SOLUTION
STEP 1: Write the given points
[tex](2,3)\text{ }and\text{ }(4,0)[/tex]STEP 2: Find the slope
[tex]\begin{gathered} \mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1} \\ \left(x_1,\:y_1\right)=\left(2,\:3\right),\:\left(x_2,\:y_2\right)=\left(4,\:0\right) \\ m=\frac{0-3}{4-2} \\ m=-\frac{3}{2} \end{gathered}[/tex]The graph of the slope is seen below:
