Question

2. If the point (3, 4) lies on the graph of equation 3y = ax +7
find the value of a.​

Answer 1

Answer:

5/3

Step-by-step explanation:

value of x 3

value of y 4

3×4=a×3 +7

12 =7 +3a

12-7 =3a

5 =3a

a =5/3

Answer 2

$\huge{ \underline{ \rm{ \red{Solution}}}}$

The given equation is → 3y = ax+7

According to the question, x = 3, y = 4

Now,Substituting the values of x and y in the equation 3y = ax+7,we get,

(3×4) = (a×3)

⇒ 12=3a + 7

⇒ 3a + 7 = 12

⇒ 3a = 12 - 7

⇒ 3a = 5

⇒ a = $\frac{5}{3}$

The value of a, if the point (3,4) lies on the graph of the equation 3y=ax+7 is 5/3.
