Question

. On the real axis, if A0,3  and B 2,7  then A B  is​

Answer 1

Answer:

Correct option is

A

0

We know, in the xy-plane, any point on the y-axis will have x=0.

Hence, any point on the y-axis is of the form (0,y), where y can be any non-zero number.

Therefore, any point whose x-coordinate is 0 and y-coordinate is non-zero will lie on the y-axis.

But here, if b=0 in the point (a,b), then it clearly lies on the x-axis.

That is, the statement is false.

Therefore, 0 is the answer.
