Answer:
m=-4/3
Explanation:
Given the points: (13,-4) and (1, 12)
To determine the slope of the line that joins the point, use the formula below;
[tex]\text{Slope},m=\frac{Change\text{ in y-axis}}{Change\text{ in x-axis}}[/tex]Substitute the given points:
[tex]\begin{gathered} m=\frac{12-(-4)}{1-13} \\ =\frac{12+4}{-12} \\ =-\frac{16}{12} \\ =-\frac{4}{3} \end{gathered}[/tex]The slope is -4/3.
