Question

The point P is on y-axis and its coordinates are given by $(3m-5,3m+1)$. Find the value of the y-coordinate.

• A. 3
• B. 4
• C. 6
• D. 5

Answer 1

The correct option is C 6

Given that the coordinates are (3m-5,3m+1)
The point P is on Y axis such that x=0
So, $3m-5=0$
$\Rightarrow 3m=5$
$\Rightarrow m=\frac{5}{3}$
Substituting the value of m in y-coordinate value,
$\left(3\times \frac{5}{3}\right)+1=6$
Option D is correct.
