Question

If the points (0,2), (1,x),(3,1) are collinear the find the value of x.

Answer 1

Answer:

x = 5/3

Step-by-step explanation:

collinear means they all lie on a straight line

us the formula:

x₁(y₂-y₃)+x₂(y₃-y₁)+x₃(y₁-y₂) = 0

0(x-1) + 1(1-2) + 3(2-x) = 0

= -1+6-3x = 0

= 5- 3x = 0

= 3x = 5

x = 5/3
