How many points are contained on a line?
20,000
none
1
infinitely many

infinitely many

Step-by-step explanation:

In geometry , A line is a straight (one dimensional ) undefined figure which has no thickness. It extends infinitely in each direction (no-endpoint).  

A point is also a undefined geometric figure that has no dimension , it helps to get the exact location of any figure on plane.

Since a line extends infinitely in both directions, so there are infinite number of points contained by it.

Thus , the number of points are contained on a line = Infinitely many

(x,(f(x)) = (0,0)

Step-by-step explanation:

let x = 0.

subst x = 0 into f(x) = 6x,

f(0) = 6(0)

f(0) = 0

Therefore, (x,f(x)) = (0,0)
