    Answer:

    The y-intercept is (0,1)

    Step-by-step explanation:

    So, first you need to find the equation! Point slope form is (y-y1)=m(x-x1).

    Plug the numbers in and you get (y-7)=3(x-2). Now, the y intercept is where x=0, so plug in zero for x.

    y-7=3(0-2)

    y-7=3(-2)

    y-7= -6.

    -6+7= 1, so y=1

    The ordered pair is then (0,1). Hope this was useful 🙂
