Answer:
slope = - [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 4, 7 ) and (x₂, y₂ ) = (8, 1 )
m = [tex]\frac{1-7}{8-(-4)}[/tex] = [tex]\frac{-6}{8+4}[/tex] = [tex]\frac{-6}{12}[/tex] = - [tex]\frac{1}{2}[/tex]
