Using a linear function, it is found that 1466 gallons of water were in the tank when jabria began adding water.
<h3>What is a linear function?</h3>
A linear function is modeled by:
y = mx + b
In which:
- m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
- b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
In this problem, we have that in 12 minutes, the amount of water increased by 3456 gallons, hence the slope is given by:
m = 3456/12 = 288.
In 7 minutes, the tank contained 3,482 gallons of water, hence the initial amount was given by:
3482 - 7 x 288 = 1466.
1466 gallons of water were in the tank when jabria began adding water.

A scatter plot is a type of graphical representation. The plot shows the negative relationship as the decrease in the outside temperature increases the bill. Thus, option d is accurate.
<h3>What is a negative correlation?</h3>
A negative correlation in a scatter plot is an inverse relationship that is seen between the two variables of the data. When one variable of the plot increases the other gets decreased and vice versa.
In the case between the temperature and the bill, the decrease in the temperature (cold) increases the heating bill as the heaters will be used more.
Therefore, option d decrease in the temperature increases the heating bill.
