Answer:
-1/5
Step-by-step explanation:
To find the slope of a line, use the slope formula.
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where [tex]x_2=-2\\ y_2=4[/tex] and [tex]x_1=13\\y_1=1[/tex].
Substitute the values and simplify:
[tex]\frac{y_2-y_1}{x_2-x_1}=\frac{4-1}{-2-13}=\frac{3}{-15}=\frac{-1}{5}[/tex]
