Question

The distance of the point $(5, 9)$ from the $y$-axis is:

• A. $14$ units
• B. $9$ units
• C. $5$ units
• D. $\sqrt{106}$ units

Hint:

The distance of a point from the $y$-axis is always equal to the absolute value of its $x$-coordinate.

Answer 1

The Correct Option is C

Step 1: Recall the concept.
The distance of any point $(x, y)$ from the $y$-axis is given by the absolute value of its $x$-coordinate. That is, \[ \text{Distance} = |x| \]
Step 2: Substitute the given coordinates.
For the point $(5, 9)$, \[ x = 5 \] \[ \text{Distance from the $y$-axis} = |5| = 5 \]
Step 3: Conclusion.
Hence, the distance of the point $(5, 9)$ from the $y$-axis is $5$ units.
