Question

Show that the points P (-3/2 , 3) , Q (6, -2) and R (-3, 4) are collinear

Answer 1

Answer:

Step-by-step explanation:

We can use the distance formula or the area of the triangle formula.

So, I'm going to use the area of the triangle formula.

if the points are collinear , then area of the triangle is 0.

area of triangle = 1/2 [x1 (y2 - y3) + x2(y3 - y1)  +  x3(y1 - y2)]

1/2 [ -3/2 (-2
