slope = tan a
where a is angle made by line with positive x axis
So
(1) 1
tan a = 1
a= 45
2) tan a = -1
a= 180 -45 = 135
3)tan a = √3
a= 60
4)tan a = -√3
a= 180 -60 = 120
5) tan a = 1/√3
a= 30
where a is angle made by line with positive x axis

its wrong
sry its right

Step-by-step explanation:
1) Let α be the inclination of a line then its slope will be tanα
tanα=1
α=45∘
2) It is tan^-1 (√3)
= 60° or π/3.
4)tan a = -√3
a= 180 -60 = 120
5) tan a = 1/√3
a= 30
