Question

A pool had 550 gallons of water. During a hurricane , water was being added at a rate of 7.7 gallons an hour. Type the number that is the slope and the y-intercept.

Answer 1

`m=7.7\\\\b=550`

Explanation:

The Slope-Intercept form of the equation of the line is the following:

`y=mx+b`

Where "m" is the slope of the line and "b" is the y-intercept.

For this exercise you need to analize the information given.

The y-axis represents the amount of gallons of water in the pool and the x-axis represnets the number of hours.

Based of the exercise, the amount of gallons of water at the beginning is 550 and when the hurricane started, 7.7 gallons are added each hour.

Therefore, when:

`x=0`,
`y=550`

Therefore, you can identify that the slope of the line and the y-intercept are the following:

`m=7.7\\\\b=550`
