Answer 2

Given,

y=4, x=8 and  x = ky

To find,

The value of k

Solution,

Since we know that x = ky satisfy the equation when y = 4 and x = 8.

Putting the respective values of x and y at their respective places we get,

⇒   x = ky

⇒   8 = k(4).

4 which is in the numerator on the right-hand side of the equation will go to the denominator on the left side hand of the equation.

⇒    8/4 = k

⇒   2 = k.

Hence, the value of k = 2.
