Show that A(2,3) B(-2,-1) and C(-3,-2) are collinear points
All you need to do is find the slope using any 2 points. Then use that slope to find the equation of the line. Then substitute each

point into the equation, and if each point makes the equation TRUE, then all points are on the line. This proves collinearity.
