Question

How do you solve this?

Answer 1

37

Explanation:

Stare at if for a while and try to find a pattern. Every time you increase x by 1, y increases by 3, so it's linear. Since at
`x=0 \rightarrow y=-3` I would assume it's

`y=3x-3` (3 as a slope is the y variation for unit increase in x, and -3 is simply the value at 0). If you keep looking at the values give all fit the model, so we're good here. Let's plug y=108:

`108= 3x-3 \rightarrow 36=x-1 \rightarrow x=37`
