Jordan lives seventeen miles away from school. this is one more mile than four times the distance sally lives from school. how many miles does sally live from school?

4 miles away

Step-by-step explanation:

To me it gives you all the information needed to anwser the question without using an x.  the anwser would be Sally lives 4 miles away.  that is because if you take jordan (17) and subtract 1 (because he lives 1 more then 4 times as far) (16) (now you have exactly 4 times as far as sally) and divide by 4 (that gives you where sally is) (4) that is the anwser for Sally.  

4 miles

Step-by-step explanation:

first you subtract 1 from 17, then you divide 16 by 4

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
