Question

determine if the points (2,3),(4,0),and (6,-3)are collinear ...plz ans step by step..

Answer 1

Answer:

Step-by-step explanation:

for proving a point collinear we need to prove that the area of triangle formed by the 3 points is zero i.e. no triangle is formed..

points are (2,3)(4,0)(6,-3)

x1=2 x2=4 x3=6

y1=3 y2=0 y3=-3

so area of triangle

0=½[x1(y2-y3) +x2(y3-y1)+x3(y1-y2)

0=[2(0+3)+4(-3-3)+6(3-0)]

0=[6-24+18]

0=0

hence points are collinear
