3x + 12 I’m guessing not sure if it’s right
First you must acknowledge that you are dealing with a line therefore you must write linear equation or linear function in this case.
Linear function has a form of,

Then calculate the slope <em>m</em> using the coordinates of two points. Let say <em>A(x1, y1)</em> and <em>B(x2, y2)</em>,

Now pick a point either <em>A</em> or <em>B</em> and insert coordinates of either one of them in the linear equation also insert the slope you just calculated, I will pick point <em>A</em>.

From here you solve the equation for n,

So you have slope <em>m</em> and variable <em>n</em> therefore you can write down the equation of the line,

Hope this helps.

We can easily get the quarts per hour rate by dividing the number of quarts by the number of hours:

Now that we have the quarts per hour rate, we can easily address the question: the factory could make

quarts in 48 hours, with a daily rate of

quarts per day
Answer:

Step-by-step explanation:
We first need to bring x up into the numerator. I will find common denominators by multiplying both sides by each denominator.

This will eliminate both denominators and leave me with
after I simplify the parenthesis.
Now I will solve the equation for x by subtracting 9x from both sides.

Then divide by the coefficient of x.
