Answer:
[tex]m=-\frac{4}{3}[/tex]
Step-by-step explanation:
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
the point (13,-4) and (1,12)
substitute the values in the formula
[tex]m=\frac{12+4}{1-13}[/tex]
[tex]m=\frac{16}{-12}[/tex]
[tex]m=-\frac{16}{12}[/tex]
simplify
[tex]m=-\frac{4}{3}[/tex]
