Question

The distance of the co-ordinate p(4,3) from the x-axis is :
A. 2 units
B. 3 units
C. 4 units
D. 5 units​

Answer 1

• p = √(x)² + (y)² = √(4)²+(3)² = √ 16+9 = √25 = 5 units
• Distance of x-coordinate is 5 units ,
• option (d) → 5 units correct ☑

Answer 2

Answer:

P = $\sqrt{x {}^{2} + y {}^{2} }$

Now p(4,3)

$= \sqrt{4 {}^{2} + 3 {}^{2} }$

$= \sqrt{16 + 9} = \sqrt{25}$

$\sqrt{25} = 5$

Hence answer is 5units
