The tangent of the angle will be ( change in y ) / ( change in x )

( this is the slope )

degrees
The inclination is = -65.556 degrees
The slope is negative, so I think the inclination would be negative, too

x1 y1 x2 y2
-2 5 3 -6

slope m = (y2-y1)/(x2-x1)
( -6 - 5 )/( 3 - -2 )
( -11 / 5 )
m= -2 1/5
slope = -11/5
Tan = -11/5
Theta = tan ^-1(11/5)
= -65.55 deg
