Like popular combinations are = 60 degrees plus 30 degrees

45 degrees plus 45 degrees.

And many more.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).

to complete this square you have to rotate about the origin 270 degrees clockwise.
