# 55.  A points A(-2, -2), B and C(2, -4) are collinear, prove that $AB=\frac{3}{7}AC$.

Dear Student,

The given question can be solved using distance formula.

Since it is given that points A,B and C are collinear, we need to find the length of AB and AC using distance formula.

Hence proved.

Hope it helps.

Regards
