Explain what the slope of each line below represents. Then find the slope and give its units

The slope represents the rate of change of water volume stored in a storage tank.

The slope here is -900 in units of gallons per month. (gal/mos)

Step-by-step explanation:

The slope is rise over run, going from left to right.

Looking at the difference in time then, it is a period of ten months, and the volume difference is -9000 gallons.

The slope then is -9000 gallons divided by 10 months, which is -900 gallons per month

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
