How to I find the degrees of a line given it's slope?
For example, a flagpole is tilted back and has a slope of -5 (with the ground being the x-axis). What is it's angle to the ground in degrees?

For a straight line when expressed in the slope-intercept form as
#y=mx+c#
we know that
Also that by definition
where
#:. theta=tan^-1m#
For the given problem
This implies that the angle
Now using tables or a calculator we get
This angle is as measured from
Or Angle of the flagpole
