First, we need to evaluate the function to get two points, and then we connect them with a line.

How to graph a linear function in math?</h3>
The linear function in the slope-intercept form is:
f(x) = a*x + b
Where x is the variable.
To graph it, we need to find two points on the line, to do that, we evaluate in two values of x. Let's use x = 0 and x = 1.
for x = 0:
f(0) = a*0 + b = b
for x = 1:
f(1) = a*1 + b = a + b
Then we have the points: (0, b) and (1, a + b).
Now we only need to graph these two points and connect them with a line, that line will be the graph of the linear function.

Complete Question
Tank A initially contained 124 liters of water. It is then filled with more water at a constant rate of 9 liters per minute. Fill in the blank with the amount of water in liters that is in tank a at the given time
How much water is in the tank
after 4 minutes?
How much water is in the tank after 80 minutes ?
Answer:
How much water is in the tank
after 4 minutes?
= 160 liters
How much water is in the tank after 80 minutes ?
= 844 liters
Step-by-step explanation:
Tank A initially contained 124 liters of water. It is then filled with more water at a constant rate of 9 liters per minute.
How much water is in the tank
after 4 minutes?
1 minute = 9 liters
4 minutes = x
x = 9 liters × 4
x = 36 liters
The amount of water in the tank after 4 minutes
= 124 liters + 36 liters
= 160 liters
How much water is in the tank after 80 minutes ?
1 minute = 9 liters
80 minutes = x
x = 9 liters × 80
x = 720 liters
The amount of water in the tank after 4 minutes
= 124 liters + 720 liters
= 844 liters
What you are doing is called cross multiplication. You have to multiply the top of the first fraction by the bottom of the second fraction. 1 x 378, which equals 378. Then you multiply the bottom of the first fraction by the top of the second fraction. 250 x X. 250x=378. You then have to solve for x or divide 378 by 250. The answer to 378 / 250 = 1.512. But the instructions want you to round to the nearest tenth and that is the first decimal place. Your answer is 1.5.
