Sagot :

Answer:

m = - [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )

( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )

m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]

~~~~~~~~~~~~~~

( - 2 , 1 )

( 2 , - 5 )

m = [tex]\frac{-5-1}{2-(-2)}[/tex] = [tex]\frac{-6}{2+2}[/tex] = - [tex]\frac{3}{2}[/tex]
