Question

Match the items given in the left column with the correct options given in the right column.

• A. $y=0$
• B. $p$ in $(p,q)$
• C. $x=0$
• D. $q$ in $(p,q)$

Answer 1

$\bullet$ In a Cartesian plane, the vertical line passing through $(0,0)$ is called the $y$-axis where value of $x$-coordinate is always zero. Any point on the $y$-axis other than origin can be represented as $(0,y)$ and the vertical line will be represented as $x=0$.



$\bullet$ Similarly, the horizontal line passing through $(0,0)$ is called the $x$-axis where value of $y$-coordinate is always zero. Any point on the $x$-axis other than origin can be represented as $(x,0)$ and the horizontal line will be represented as $y=0$..


$\bullet$ A point is denoted as $(p,q)$ or $(x,y)$ where the first number $p$ denotes the $x$-coordinate.


And the second number $q$ in $(p,q)$ denotes the $y$-coordinate.
