Answer:
10 gallons per minute
y = 10x
Step-by-step 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
