First, let's factor both of these numbers.
256x:

144x:

Both of these numbers contain

, so that would be the greatest common factor. This could also be written as 16x.
Answer:
C
Step-by-step explanation:
Option C is the only one that's linear because it follows all of the rules for a line to be linear. To check, use the process of elimination:
A). When x is an absolute value, the line will not be linear because an input will have two outputs.
B). x cannot be in the denominator of a fraction for the line to be linear
D). Once again, x cannot be an absolute value.
*Note: I'm assuming in option B, 7x is in the denominator and 1 is in the numerator. If the fraction is simply 1/7 multiplied by x, it is linear along with C.
