Answer 1

SOLUTION

GIVEN

The point (3, 2) lies on the graph of the equation 5x + ay = 19

TO DETERMINE

• The value of a

• Write the equation of the line

EVALUATION

Here the given equation of the line is

5x + ay = 19

Now the point (3,2) lies on the graph of the equation 5x + ay = 19

Thus we get

( 5 × 3 ) + ( a × 2 ) = 19

⇒ 15 + 2a = 19

⇒ 2a = 4

⇒ a = 2

Also the equation of the line is

5x + 2y = 19

FINAL ANSWER

Hence the required value of a = 2
