Finding the angle of inclination from two end points of a line.

 point1 = [22, 114];
 point2 = [693, 233];

 x1 = point1(1);
 y1 = point1(2);
 x2 = point2(1);
 y2 = point2(2);

 slope = (y2 - y1) ./ (x2 - x1);

 angle = atand(slope)

Output

 angle = 10.0567

This line has a negative slope. Why am I getting an incorrect answer?

With those point coordinates and the way you define slope it has positive slope. If you want to force it to have negative slope then you need to define your point coordinates differently.

Oh! I got it!!

This code works well... Thank you

point1 = [22, -114];
point2 = [693, -233];
x1 = point1(1);
y1 = point1(2);
x2 = point2(1);
y2 = point2(2);
slope = (y2 - y1) ./ (x2 - x1)
angle = atand(slope)
