No the points are not collinear because the area is not equal to zero.

Step-by-step explanation:
Area of triangle when coordinates of point are given =1/2[x1(y2-y3)+X2(y3-y1)+x3(y1-y2)]
If the points are collinear then their area is 0sq.units.
Area=1/2[1(-2-(-3)+5(-3-5)+(-2)(5-(-2))]
=1/2[1+5(-7)+(-2)(-7)]
=1/2[1-35+14]
=1/2[-35+15]
=1/2[-20]
=-10sq units.
The given points are not collinear.
