For this case we have that by definition, the equation of the line in the slope-intersection form is given by:

Where:
m: It is the slope of the line
b: It is the cut-off point with the y axis
We have the following points through which the line passes:

We find the slope of the line:

Thus, the equation of the line is of the form:

We substitute one of the points and find b:

Finally, the equation is:

Answer:

Answer: 4,032
Step-by-step explanation:
8,4 x 0,48 = 4,032
Answer:
y = (4x - 9) / 5 or y = 4/5x - 9/5
Step-by-step explanation:
Solving for y
4x - 5y = 9
-5y = -4x + 9
5y = 4x - 9
y = (4x - 9) / 5 or y = 4/5x - 9/5
The equation in the function form is f(x) = -3x + 15 and the tub started with 15 gallons of water.
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have an equation:
y –12 = –3(x – 1)
We can write the above equation as follows:
y = 12 - 3(x - 1)
y = 12 - 3x + 3
y = -3x + 15
or
f(x) = -3x + 15
Plug x = 0
f(0) = 15
The tub started with 15 gallons of water.
Thus, the equation in the function form is f(x) = -3x + 15 and the tub started with 15 gallons of water.
