Answer:

slope = - $\frac{7}{5}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, - 7 ) ← 2 points on the line

m = $\frac{-7-0}{0-(-5)}$ = $\frac{-7}{0+5}$ = $\frac{-7}{5}$ = - $\frac{7}{5}$
