Astudent is running a 5 kilometer race. he runs 1 kilometer every 3 minutes. select the function that describes his distance from the finish line after x minutes

The first one f(x) = -1/3x + 5

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
