Question

Find the value of x such that the points (0, 2), (1, x) and (3, 1) are collinear.

Answer 1

Answer:

x=5/3

Step-by-step explanation:

A(0,2);B(1,x);C(3,1)

Slope of line AB=Slope of line BC

y2-y1/x2-x1=y2-y1/x2-x1

x-2/2-1=1-x/3-1

x-2/1=1-x/2

2(x-2)=1-x

2x-4=1-x

2x+x=1+4

3x=5

x=5/3
