Find the slope of the line that passes through Point A $$(−5,7) and Point B $$(2,5), using the formula $$m=

tester [92]

Answer:

slope = - $\frac{2}{7}$

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, 7 ) and (x₂, y₂ ) = (2, 5 )

m = $\frac{5-7}{2-(-5)}$ = $\frac{-2}{2+5}$ = - $\frac{2}{7}$
