as  (-3 , 5) ,  (-3 , 5) &  ( 0 , 3)  are collinear so these points are not a quadrilateral

Step-by-step explanation:

Show that the points (-3,5),(3,1),(0,3),(-1,-4) are not a quadrilateral

Four points will be Quadrilateral if not more than two pints are collinear

A = (-3 , 5)

B = ( 3 , 1)

C = ( 0 , 3)

D = ( - 1 , - 4)

Slope of AB  =  ( 1 - 5)/(3 -(-3)) = -4/6  = -2/3

Slope of BC  = (3 - 1)/(0 - 3) = 2/(-3) = -2/3

Slope of AB = Slope of BC

=> points A , B & C are collinear

=>  (-3 , 5) ,  (-3 , 5) &  ( 0 , 3)  are collinear

hence these points are not a quadrilateral
