Question

If the points a(x, 2), b(3, 4) and c(7, 5) are collinear, then the value of x is:

Answer 1

Step-by-step explanation:

If three points are Collinear then the area of the triangle formed by these points is equal to zero.

Area of triangle = 1/2 [(4x-6)+(15-28)+(14-5x)]

0=1/2[4x-6-13+14-5x]

0= - x-5

X=5.
