Question

Match the sign of $x$ and $y$ coordinates in different quadrants.

• A. $(-,-)$
• B. $(-,+)$
• C. $(+,-)$
• D. $(+,+)$

Answer 1

$\bullet$ To move to $\underset{–}{\text{quadrant 1}}$ from origin, we need to move $\underset{–}{\text{right in the}x\text{-axis}}$ and $\underset{–}{\text{up along the}y\text{-axis}}$. So, in the first quadrant, both $x$ and $y$ coordinates are positive.

$\bullet$ To move to $\underset{–}{\text{quadrant 2}}$ from origin, we need to move $\underset{–}{\text{left in the}x\text{-axis}}$ and $\underset{–}{\text{up along the}y\text{-axis}}$. So, in the second quadrant, $x$ coordinate becomes negative and $y$ coordinate remains positive.

$\bullet$ To move to $\underset{–}{\text{quadrant 3}}$ from origin, we need to move $\underset{–}{\text{left in the}x\text{-axis}}$ and $\underset{–}{\text{down along the}y\text{-axis}}$. So, in the third quadrant, both $x$ and $y$ coordinates are negative.

$\bullet$ To reach at $\underset{–}{\text{quadrant 4}}$ from origin, we need to move $\underset{–}{\text{right in the}x\text{-axis}}$ and $\underset{–}{\text{down along the}y\text{-axis}}$. So, in the fourth quadrant, $x$ coordinate becomes positive and $y$ coordinate becomes negative.
