Asegment with endpoints x(-6,2) and y(-1,-3) is rotated 90 degree about the orgin. what are the coordinates of x and y?

The line segment has has an equation:
y = -x - 4

The line intersects the x-axis at x = -4
Rotating 90 degrees along the origin, the x-intercept would be y-intercept wit the negative sign.
The line segment passes through (0, 4)
The new coordinate of X is (2, 6) and the new coordinate of Y is (-3, 1)
