Question

determine whether the points are collinear. (0,4) (7,6) (5,11)

Answer 1

@ParthKohli @mathteacher1729 @amistre64

Answer 2

How about drawing the thing out?

Answer 3

I did they look like they are in a straight line

Answer 4

but I could be wrong.

Answer 5

those look non-collinear

Answer 6

They do?

Answer 7

Yeah, they do. And that is the answer.

Answer 8

so, it is non-collinear?

Answer 9

Yep

Answer 10

thx

Answer 11

@ParthKohli is right as always, they are not collinear.

Answer 12

@schmidtdancer Woah, you need more than that to SHOW that they are non-collinear!

Answer 13

You can do this a few ways.

1) Pick two points, find the equation of line between them, then see if the third point is on that line.

2) Name the points A, B, and C. Find the distance between AB, and BC. If that distance is EQUAL to the distance between AC, then they are colinear. Otherwise, not.

Answer 14

\(AB \ne BC\) but \(ABC \) forms a straight line @mathteacher1729
