Question

If the point (3, 5) lies on the line of the equation 3y = ax + 9, the value of a is ___.

• A. 0.0
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is B 2

If the point lies on the line then it satisfies the given equation,
Substituting x = 3, y = 5 in the given equation, we get
$3\times 5=a\times 3+9$
$\Rightarrow$ 3a + 9 = 15
$\Rightarrow$ a = 2
