Answer:
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
