Question

The table below shows the relationship between the approximate number of hours and the corresponding number of days on Saturn.

Saturn
Hours
Days
266 and two-thirds
25
373 and one-third
35
426 and two-thirds
40
586 and two-thirds
55

What is the approximate number of hours in 72 days on Saturn?
603 and two-thirds
658 and two-thirds
743
768

Answer 1

the table is kind of hard to understand, but treat hours as the x-values and days as the y-values

pick two points from the table, and write an equation in y = mx + b form

for starters, use the slope formula to calculate m
then use y = mx + b, along with one of the points, and calculate b
then write the y = mx + b equation by filling in m and b

once you have the equation, you can simply let y = 72 days and calculate x
