Hola User_______________________

Here is Your Answer.....!!!!
_________________________________

〽Actually welcome to the concept of the Straight lines ....

〽Basically for the slope ...we know .....we can use the Tan ratio for the following questions .....

〽13)
Side of a Equilateral triangle parallel to X - axis ....

〽AB || OX
THUS BOTH WILL HAVE THE SAME SLOPE .....

〽There fore .... slope of AB = Tan (0)° = 0
slope of AB = 0.....

〽Slope of side AC ...making inclination of 60° with the x - axis ....
thus slope of AC = Tan (60)° = _/3
slope of AC = underoot 3

〽Slope of BC as it is making Angle 120°

〽thus slope of BC = Tan (120)° = -Tan (60)° = -_/3

〽slope of BC = Negative of underoot 3....

14)

〽In the given square .....

〽Side AD and BC are perpendicular to the x-axis .....Thus they slope as

〽Tan (90)° = Undefined ....or infinite ...
thus slope if AD and BC = UNDEFINED ...

〽Slopes of side AN and DC are parallel to x-axis ..thus they have slope as ZERO..
