Question 3:
Determine if the points (1, 5), (2, 3) and (− 2, − 11) are collinear.
Answer:
Let the points (1, 5), (2, 3), and (−2, −11) be representing the vertices A, B, and C of the given triangle respectively.
Let A = (1,5), B = (2,3), C = (−2, −11)
Therefore, the points (1, 5), (2, 3), and (−2, −11) are not collinear.
