Maths · Cartesian system of rectangular coordinates in a plane

Are the points (1,1),(2,3) and (8,11) collinear?

Are the points (1,1),(2,3) and (8,11) collinear?

  • A. collinear
  • B. Non collinear
  • C. coplaner
  • D. None of above

Step-by-step solution

Compute slopes: slope between (1,1) and (2,3) = 2; slope between (1,1) and (8,11) = 10/7 ≈ 1.4286. Since slopes are not equal, the points are not collinear.
