Find the obtuse angle between the y- axis and the line with a slope of m= -1/4?
------------------------------
Plot the point (4,-1) and (0,0)
Draw a line thru them so you can see what is happening.
---
invtan(-1/4) = -14.04 degrees is the acute angle.
----
180-14.04 = 165.96 degrees is the obtuse angle.
