Y is directionally proportial to x, when y = 30 and x = 6, work out an equation connecting x and y

y = 5x

Step-by-step explanation:

The standard equation for directly proportional equations is y = kx. We can see that y is directionally proportional to x when y = 30 and x = 6 and we need to work out an equation connecting x and y.

→ First step is to substitute in the values

y = k * x

30 = k * 6

→ Divide both sides by 6 to isolate k and find the value of k

5 = k

k = 5

→ Now we substitute k = 5 back into y = kx

y = 5x

y=5x

Step-by-step explanation:

The answer is y=5x hope you have a nice day!
