Question

3 Determine, if the points (1,5), (2, 3) and (-2 -11)
are collinear.​

Answer 1

Answer:

using slope formula we can find whether these points are collinear or not

Step-by-step explanation:

slope =y2 - y1/x2 - x1

let the points be a (1,5) , b(2,3) and c(-2,-11)

the slope of ab =3-5/2-1 =-2

the slope of bc = -11-3/-2-2 =-14/-4 =7/2

therefore the points are not Collier
