Question

find the value of a and b if the point a(2-,1) b(a,b) c(4,-1) are collinerar and a-b =1​

Answer 1

Answer:

The given points are A (−2, 1), B (a, b) and C (4, −1). Since the given points are collinear, the area of the triangle ABC is 0. Thus, the values of a and b are 1 and 0, respectively.
