Question

Write an equation for the direct variation 120,000 divided by 10

Answer 1

10 gallons per minute

y = 10x

Explanation:

Robert fills the pool at the rate of 10 gallons each minute

So rate at which Robert will fill the pool is 10 gallons per minute

when x= 1 minute , gallons of water y = 10

x= 2 minute , y= 10*2 = 20

x=3 minutes , gallon of water filled = 10*3 = 30

the graph is attached below

Formula for direct variation is y=kx

Where k is the rate of constant = 10

so equation becomes y = 10x
