Question

Just answer no need to explain lol

Answer 1

The fixed costs are represented by b.

Addition of $28,000 means, we are adding 28 to the given function. Addition/Subtraction of a number to the function brings only vertical shift not the horizontal shift.

Addition bring upward shift and Subtraction brings downward shift. So, increase of $28,000 will bring an upward shift of 28 units.

So, the correct answer is option C

Answer 2

The correct answer for the question shown in the image attached is the third (option C), which is:

 C. Shifted upwards by 28 units

 The explanation is shown below:

 1. The problem gives you the following linear function:

 f(x)=ax+b

  Where a is the slope and b is the y-intercept

 2. When you graph that linear function, you obtain a line.

 3. Therefore, if b (y-incercept) increases 28,000; the line will shifted 28 units upwards.

 4. As you can see, the correct answer is the option mentioned above.
