This is a nice problem to test the understanding of the translation of a function.
In general, a transformation
f(x)->g(x) where g(x)=f(x-h)+k
involves a translation of h units to the right, and k unit up.

In the case of a straight line, we do not see separate effects of horizontal or vertical translations, because the image g(x) remains parallel to the original function f(x).

The translation of f(x)=-2x+7 -> g(x)=f(x-h)+k 
can be visualized as
g(x)=-2(x-h)+7+k
which by expansion
g(x)=-2x+2h+7+k
Since we have the image 9 units BELOW f(x), we equate
f(x)-9=-2x+2h+7+k=g(x)
=>
-2x+7-9=-2x+2h+7+k
on simplification =>
2h+k=-9
From the given answer options,
a. h=-5, k=1 => 2h+k=-10+1=-9  [ equals -9, so OK]
b. h=4, k=1 => 2h+k=8+1=9        [does not equal -9, so NOT THIS ONE]
c. h=-2, k=2 => 2h+k=-4+2=-2     [does not equal -9, so NOT THIS ONE]
d. h=-9, k=2 => 2h+k=-18+2=-18  [does not equal -9, so NOT THIS ONE]

1. Try It # 1 A company sells doughnuts. They incur a fixed cost of $25,000 for rent, insurance, and other expenses. It costs $0
Y_Kistochka [10]

Answer:

The y-intercept is 25000 . The intercept is the fixed cost of the doughnut selling company.

Step-by-step explanation:

In the question, it is given that the fixed cost is $25000 and the expense to produce each doughnut is $0.25.

It is required to find and identify the y intercept.

To do so, use the equation derived in previous part of the exercise to interpret the slope. Compare the equation with standard equation of the line.

Step 1 of 1

The total cost of the company is the sum of fixed cost and the expenses for the doughnut, C=0.25x+25000.

Compare the equation with general linear equation y=mx+c.

The y-intercept is 25000 .

The intercept is the fixed cost of the doughnut selling company.
