Find the slope of any line parallel to the line through points (17, 4) and (5, 8).

the slope of these is:

8-4 4 1

----- = --- = ---

17-5 12 3

is 1/3 the correct answer?

No

you started with the y of the second point, so you have to start with the x of the second point also

slope = (8-4)/(5-17) = - 1/3
