Answer:
slope = - [tex]\frac{11}{4}[/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 ) = (- 18, 7 ) and (x₂, y₂ ) = (- 10, - 15 )
m = [tex]\frac{-15-7}{-10-(-18)}[/tex] = [tex]\frac{-22}{-10+18}[/tex] = [tex]\frac{-22}{8}[/tex] = - [tex]\frac{11}{4}[/tex]
