Hello!

Explanation:

Slope:
(Y^2-Y^1)/(X^2-X^1)=(rise)/(run)


(1-8=-7)/(2-(-3)=2+3=5)=(-7)/(5)=-(7)/(5)

Slope is -7/5

Answer is -7/5

Hope this helps!

Thanks!

\bf \begin{array}{lllll} &x_1&y_1&x_2&y_2\\ % (a,b) &({{ -3}}\quad ,&{{ 8}})\quad % (c,d) &({{ 2}}\quad ,&{{ 1}}) \end{array} \\\\\\ % slope = m slope = {{ m}}= \cfrac{rise}{run} \implies \cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{1-8}{2-(-3)}\implies \cfrac{1-8}{2+3}\implies \cfrac{-7}{5}
