slope=oo

Explanation:

P_1=(-2,5)" the point of " P_1
P_2=(-2,8)" the point of "P_2

slope=(P_"2y"-P_"1y")/(P_"2x"-P_"1x")

slope=(8-5)/(-2-(-2))

slope=3/0

slope=oo

Slope of line joining (-2,5) and (-2,8) is oo i.e. it is perpendicular to x-axis.

Explanation:

Slope of line joining (x_1,y_1) and (x_2,y_2) is given by

(y_2-y_1)/(x_2-x_1)

Hence slope of line joining (-2,5) and (-2,8) is

(8-5)/((-2)-(-2))=3/(-2+2)=3/0=oo

Hence, slope of line joining (-2,5) and (-2,8) is oo i.e. it is perpendicular to x-axis.
