If the signs of the coordinates of collinear points p(-6,-2), q(-5,2), and r (-4,6) reversed, are the 3 new points still collinear?

The new points also collinear.

Step-by-step explanation:

The given points are P(-6,-2), Q(-5,2), and R (-4,6) are collinear.

If three point are collinear, then

If the signs of the coordinates of collinear points P(-6,-2), Q(-5,2), and R (-4,6) reversed, then the new coordinates are P'(6,2), Q'(5,-2), and R'(4,-6)

Using the formula, check whether the new points are collinear or not.

Since LHS=RHS, therefore the new points are collinear.
