Using the method of slopes show that the following points are collinear:
A(4, 8), b(5, 12), C(9, 28)
We have three points given A(4, 8), b(5, 12), C(9, 28)
To Prove: Given Points are collinear
Proof: A(4, 8), B(5, 12), C(9, 28)
The formula used: The slope of the line = ![]()
The slope of line AB = ![]()
AB = ![]()
The slope of line BC = ![]()
BC =
= 4
The slope of line CA = ![]()
![]()
Here, AB = BC = CA
Hence, The Given points are collinear.
