Answer:
Step-by-step explanation:
I think the question below is the one you wanted to ask:
A pool has some initial amount of water in it. Then it starts being filled so the water level rises at a rate of 6 centimeters per minute. After 20 minutes, the water level is 220 centimeters
Graph the pool's water level (in centimeters) as a function of time (in minutes).
Here is my answer:
To draw the linear line, we need to identify the equation that modles this situation. As we know the water level rises at a rate of 6 cm per minute which mean the slope m = 6
The standard form is: y = mx + b <=> y = 6x + b
After 20min the water level is 220 cm
<=> 220 = 6(20) +b
<=> b = 100
So your equation is : y = 6x + 100 and the initial amount of water in it is 100
