The points are (9,12) and (-12,9).
The answer is A.
Remark
The way this is written I would assume that it means 4*f(x) = x. That may not be entirely the correct assumption to be made.
Step One
Replace f(x) by 4f(x)
4*f(x) = x
Step two
Divide both steps by 4
f(x) = x/4 or (1/4)x
The slope is now 1/4
Discussion
A is incorrect.
The slope has been changed.
B is incorrect
The slope has been changed to 1/4 and the y intercept is still 0
C looks to be the right answer.
D The y intercept is still zero.
Comment
The question is a little hard to interpret. I've read it literally. That means that I have taken the question to mean that only f(x) was altered. If however, the right side was multiplied by 4 as well (as should be done), then the answer is A same slope same intercept. That's because the 4s on the left and right cancel, and the original equation results. I'm going to pick C but don't be surprised if it is A

Answer:
6 cm
Step-by-step explanation:
A = 1/2(b + 12)(4)
36 = 1/2(b + 12)(4)
72 = (b + 12)(4)
18 = b + 12
18 - 12 = b
6 = b
or
b = 6 cm
Answer:
x = -11, y = 10, z = 4
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
$29.43
Step-by-step explanation:
5 1/2 % or 5.5% is 0.055 as a decimal. Multiply 535 by 0.055 to find what 5.5% of 535 is...
0.055(535) = 29.425
Since we're working with dollars, round to the nearest hundredth, which is
$29.43
