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 )

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