Step 1: \ \

The points are and \ \

and \ \

Condition collinearity of three points is . \ \

Let the points be and \ \

Substitute the values in above condition. \ \

\ \

\ \

and are not collinear. \ \

No, these points donot lie on a straight line. \ \

Solution: \ \

No, the points and donot lie on a straight line. \ \
