State whether the statements are true or false.
The points A (– 2, 1), B (0, 5), C (– 1, 2) are collinear.
Given points are A(-2,1), B (0,5) and C(-1,2)
There are two ways to find that given points are collinear or not .
The first is if 3 points are collinear, then slope of any two pairs of points will be equal.
Second way is that if the value of area of triangle formed by the 3 points is zero, then the points
are collinear.
Slope of AB
Slope of BC
Slope of CA is
Since, the slopes are different.
So, the given points are not collinear
Hence, the given statement is False
