no its not colinear because both magnitude of ac is not equal to magnitude of ab2+ac2

using formula
1/2 { x1( y2-y3) +x2(y3-y1) +x3(y1-y2)}=0
put the values,
x1=0,x2=1 and x3=2,
y1=2,y2=0.5 and y3= - 3
if you get it zero that means they are collinear otherwise not.
hope it will help you!

sorry it is x3(y1-y2)
