Question 525766
it looks like you saw that y changes by 4 when x changes by one


that means that x is multiplied by 4 to get y


but there is also a "fudge factor" added in (a constant term)


if you look at the pairs, you can find the factor


y = 4x + ? ___ 7 = 4(1) + ? ___ 11 = 4(2) + ? ___ the factor is 3


so the formula is ___ y = 4x + 3
