Coordinate axes and Cartesian plane

Q.

Assertion: The graph of the two linear equations x - 2y = 1 and 2x + 3y = 9 intersect at (3, 1).

Reason: Every point lying on x - 2y = 1 is a solution of 2x + 3y = 9

Now, choose the correct option.

1. Both the assertion and the reason are true and the reason is the correct explanation for the assertion.
2. Both the assertion and the reason are true but the reason is not the correct explanation for the assertion.
3. Assertion is true but the reason is false.
4. If assertion is false but reason is true.

Q.

Assertion: All the points (1, 0), (-1, 0), (2, 0) and (5, 0) lie on the x – axis.
Reason: Equation of the x-axis is y = 0

Choose the correct option.

1. Both assertion and reason are correct and reason is the correct explanation of assertion.
2. Both assertion and reason are correct, but reason is not the correct explanation of assertion.
3. Assertion is correct but reason is incorrect.
4. Assertion is incorrect but reason is correct.
