MATH PLEASE HELP

posted by .

x = 2 , 4 , 6 , 8
y = 18, 34, 50, 66

This is supposed to be a table where the x lines up with the y in order

How would I find the equation to solve this when x = 20?

x goes up by +2
y goes up by +16 but starts with 18

    The relationship is
    y = 2 + 8 x

    if x = 18, y = 146

    Also, how did you come up with the equation?

    Where did the 8 and 2 come from?

  • MATH PLEASE HELP -

    I understand now

    Good.
    8 was the obvious slope.
    I picked the constant term 2 so that any one of the (x,y) combinations would match.
