Question

If a point (1,3$k$) lies on $kx+4y=26$, the value of $k$ is

• A. 2
• B. -2
• C. 3
• D. -3

Answer 1

The correct option is A

2

If the point (1,3$k$) lies on the given line, then it must satisfy the equation.

Putting the value of $x$ and $y$ in the given equation:
$\Rightarrow k\left(1\right)+4\left(3k\right)=26$
$\Rightarrow 13k=26$
$\Rightarrow k=2$

Thus, the value of $k$ is 2.
