we know that
the formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
in this problem we have
[tex]A(-3,5)\ B(5,-3)[/tex]
substitute the values in the formula
[tex]m=\frac{-3-5}{5+3}[/tex]
[tex]m=\frac{-8}{8}[/tex]
[tex]m=-1[/tex]
therefore
the answer is the option
[tex]slope=-1[/tex]
