Question

How do I write a direct variation equation? Y=10 when x=2

Answer 1

The basic formula for direct variation is y=kx (k=constant), right?

Answer 2

So, 10=k*2 -------> k=5

So, the equation is y=5x

Answer 3

I'm not sure

Answer 4

ok a direct variation equation would be written like this on a graph
\[y=kx ,y=mx , m=slope , k=constant\]

Answer 5

It says suppose y directly varies with x. Write a direct variation equation that relates x and y. Then find the value of y when x=8
