Question

if(3,2) ,(4,k) and (5,3) are collinear then k is equal to :

Answer 1

see... the formula of area of triangle in coordinate geometry is 1/2{x1(y2-y3)+x2(y1-y3) +x3(x1-x2) so area of triangle will be equal to zero because it's collinear so you can find the answer by putting 1/2{x1(y2-y3)+x2(y1-y3)+x3(y1-y2) = 0 I hope it helps...mark as brainliest if it really helps

Answer 2

if the points are collinear . then area of triangle is o. the next process is explained in the photos.
if the answer helps you then mark the answer as brainliest.
