    all you have left is number 4, so for that think of a linear equation and write it as a progression

    i should say, write out the y values for the corresponding x = {1,2,3 ... n-1, n} as a progression

    so if you choose 2x + 1, then for x = {0,1,2,3} you would write the progression y = {1,3,5,7}

    does that make sense? your just plugging in values, y is just x augmented by a function (in this case 3x + 2)

    a progression is just a sequence of numbers with equal spacing, like 0,1,2,3,4 is each term plus 1

    thinkk of this as your x axis, 0,1,2,3...exc,

    what a function does is takes this progression and relates it to another progression, 3x for example is a function that takes each number on your x axis and multiplies it by three

    so your second progression, think of it as your y axis, is really just the x axis multiplied by three
