Question

By using the concept of equation of a line prove that the three points (3,0) (-2,-2) and (8,2) are collinear

Answer 1

Hi Friend !!!

Here is ur answer !!!

Line eqn of (3,0) and (-2,-2) is

y-o = 2/5 (x-3)

5y = 2x-6

2x-5y-6 = 0

put (8,2) in the equation

2(8)-5(2)-6 = 16-16 = 0

It satisfies the given equation so they are collinear points

Hope it helps u :-)

Answer 2

Answer:

use the formula

y-y,=y2-y1/x2-x1(x-x1)

if your answer comes 0 then the lines are collinear
