Answer:

Step-by-step explanation:

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

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

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

parallel lines have the same slopes , perpendicular lines have slope which are opposite reciprocals.

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

A( 3 , 5 )

B( - 2 , 7 )

$m_{AB}$ = $\frac{7-5}{-2-3}$ = - $\frac{2}{5}$

C( 10 , 5 )

D( 6 , 15 )

$m_{CD}$ = $\frac{15-5}{6-10}$ = - $\frac{5}{2}$

The answer is (A) Neither
