Answer 1

have a particular one in mind?

Answer 2

i'll just tell you what you would need to do i guess.
you have to find the relationship between x and y in a table.
and from there write the function as
y = ax + b

let's say you have
the table
x | y
1 2
2 3
3 4
each change in x results in an addition of 1 to get the y value so

y = x + 1
let's test it

y = 1 + 1
y = 2 ✓

Answer 3
