Answer:
slope = - [tex]\frac{4}{3}[/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 ) = (7, 12 ) and (x₂, y₂ ) = (19, - 4 )
m = [tex]\frac{-4-12}{19-7}[/tex] = [tex]\frac{-16}{12}[/tex] = - [tex]\frac{4}{3}[/tex]
