we have a point(x,y) and length of the line is L and the angle between horizontal line and the draw line is A.

Fine. What is your question? What have you tried so far and which problem occurres?

There is a line function you know. Just specify the two endpoints, which can be computed from simple trig.
line([x1,x2], [y1,y2], 'Color', 'r', 'LineWidth', 2);

%L is the length
%angle is alpha
x2=x+(L*cos(alpha));
y2=y+(L*sin(alpha));
plot([x x2],[y y2])

This works perfectly!
Note: instead of sin(alpha), cos(alpha), use sind(alpha) and cosd(alpha) to avoid the floating point errors of the sin and cos values.
