Question

Find the slope of the line passing through the points ( 9, -5) and (1, -1)

Answer 1

Answer:

m = - $\frac{1}{2}$

Step-by-step explanation:

( $x_{1}$ , $y_{1}$ )

( $x_{2}$ , $y_{2}$ )

m = $\frac{y_{2} -y_{1} }{x_{2} -x_{2} }$

~~~~~~~~~

( 9 , - 5 )

( 1 , - 1 )

m = ( - 1 - ( - 5 ) ) / ( 1 - 9 ) = - $\frac{1}{2}$
