Question

Draw any line and mark any 3 points that are collinear

Answer 1

Answer:

The points $(0,0), ~(1,1)$ and $(2,2)$ are collinear and pertence to the line $r: x-y = 0$.

Step-by-step explanation:

Three points are collinear if we can draw one line through them. So if we draw a line at first, and then mark three points on it, they will be collinear by constrution.

Then, consider the line $r: x -y = 0$ and the three points $(0,0), ~(1,1)$ and $(2,2)$, which pertence to the line. These points are collinear, as required.
