Question

Assertion :By using graph we can locate $(0,4)$ on the y-axis. Reason: A point whose y-coordinate is zero lies on the x-axis.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

Answer: (B)

Obviously, by using graph, we can easily locate $(0,4)$ on the $y$-axis,

as any point on the $y$-axis has the form $(0,a)$, where $a$ is any number. Hence, it is correct.

Also, a point whose $y$-coordinate is zero lies on the $x$-axis,

as any point on the $x$-axis has the form $(a,0)$, where $a$ is any number. Hence, it is correct.

But clearly, the reason is not the correct explanation for the assertion.

Therefore, option $B$ is correct.
