Answer:
option a. [tex]-\frac{5}{4}[/tex]
Step-by-step explanation:
we know that
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
we have
the points (1, 3) and (5, –2)
substitute
[tex]m=\frac{-2-3}{5-1}[/tex]
[tex]m=\frac{-5}{4}[/tex]
[tex]m=-\frac{5}{4}[/tex]
