Question

If the points (k + 2, k +1), (k + 3, k) and (k + 4, k – 1) are collinear, then the value of k is
a. -3
b. an integer only
c. any real number
d. None of these

S D · Answer

C. The area of the triangle formed by these 3 points should be zero. Apply the determinant formulae.

If the points (k + 2, k +1), (k + 3, k) and (k + 4, k – 1) are collinear, then the value of k is a. -3 b. an integer only c. any real number d. None of these
