The 2 points on the line given are:
[tex]\begin{gathered} (a,b_{})=(4,3) \\ \text{and} \\ (c,d)=(2,7) \end{gathered}[/tex]The slope formula can be used to find the slope. We can write the slope formula as:
[tex]m=\frac{d-b}{c-a}[/tex]Substituting the values, we get the slope of the line:
[tex]\begin{gathered} m=\frac{7-3}{2-4} \\ m=\frac{4}{-2} \\ m=-2 \end{gathered}[/tex]
