The dwarf planet Makemake completes one orbit around the Sun every 310 years. Which of the following functions r models the number of orbits of Makemake in t years?

Answer:
3rd option, r(t) = 310t
Step-by-step explanation:
310 years is like the slope so you multiple it by the amount of years
example: in 2 years it would make 620 orbits since 310(2) = 620
