A) x-axis
B) y-axis
C) The line y = x
D) ​​​​​​​The line x + y = 0​​​​​​​

Q.

The point of the form $(a,a)$, where $a\ne 0$ lies on:

1. $x$-axis

2. $y$-axis

3. The line $y=x$

4. The line $y=-x$

Q.

Consider the following two statements:

Statement-1: An equation of the form $ax+by+c=0$, where $a,b$and $c$ are real numbers, such that $a,b$and $c$ are variables and $x,y$ are constants is called linear equation in two variables.

Statement-2: The graph $x=a$ is a straight line parallel to the $x$-axis.

Which of the following is correct?

1. Statement 1 is true and Statements 2 is false.

2. Statement 1 is false and Statements 2 is true.

3. Both statements 1 and 2 are true.

4. Both statements 1 and 2 are false.
