plz help me in stuck this is hard for me

Answer 1

#1 just plug in various values for n.

#2 note that as x increases by 2, y decreases by 1. So, you'd expect something like

y = -1/2 x
But, -1/2 * 2 = -1, and y = 1, so adjust the rule to be

y = -1/2 x + 2

#3 just multiply 159 by the number of seconds.

Answer 2

IM STILL CONFUSED ABOUT THE SECOND ONE
