Question

In a direct variation, y = 20 when x = 2. Write a direct variation equation that shows the
relationship between x and y.
Write your answer as an equation with y first, followed by an equals sign.

Answer 1

Answer:

Y=10x

Step-by-step explanation:

Direct variation equations are written. y=kx

y=20

x=2

20=2k

dividing both the sides by 2

we get

10=k

we can have k in the original equation and say y=10x
