Question

Y is directly proportional to X when y=30,X =6 work out an equation connecting y and X

Answer 1

Y directly proportional to X

Y=kX ( k =constant)

30=6k

k=30/6

k=5

Answer 2

Answer: Our required equation would be $y=5x$

Step-by-step explanation:

Since we have given that

y=30, when x = 6.

As there is direct proportion between x and y.

so, it becomes,

$\dfrac{y}{x}=k\\\\\dfrac{30}{6}=k\\\\k=5$

So, the equation connecting y and x would be

$y=kx$

When we put the value of k, we get that

$y=5x$

Hence, our required equation would be $y=5x$
