anonymous · Answer

do you see a trend in the numbers for "y"?

anonymous · Answer

yes. 26

anonymous · Answer

you mean a constant difference of 26.
this means that "x" and "y" are linearly related

anonymous · Answer

you see,
$y=x\times26$

anonymous · Answer

yes. i already got that part ... i just need to know how to get the miles

anonymous · Answer

its either 200 , 252 , 300 , or 312

anonymous · Answer

good 
"x" represent the number of gallons
and
"y" represent the numbre of miles for that many gallons

anonymous · Answer

so, the question gives you 
x=12
and asks you to find "y"

anonymous · Answer

i think so ;o

anonymous · Answer

thats what it is
so, we plug in 12 for x
$$y=12\times26=?$$

anonymous · Answer

312 ?

anonymous · Answer

yep

anonymous · Answer

so thats the answer ?

anonymous · Answer

yes.
the value for "y" 
when x=12 is the answer

that is what you just calculated

anonymous · Answer

okay. thanks :)
