Given Coordinates:(3, 2)

Therfore, x=3 and y=2

Given Equation:5x+ay =19

Substitute the values,

5(3) + a(2) = 19

15 + 2a = 19

2a = 4

a=2

Which is the required answer.

Answer 2

Answer:

The value of a when point (3,2) lies on the graph is a=2.

Step-by-step explanation:

The point satisfies the given equation.

⇒ If the values of the point is substituted in the equation, value of a is obtained.

The given equation is 5x+ay= 19

Substituting x=3 and y=2 in the given equation we get,

$5\times3+a\times2 = 19$

$15+2a=19$

$2a=4$

a=2

The value of a=2.

The correct answer is a=2.
