    Take slope-intercept form and start plugging things in.

    You have a point (-7,0) so x = -7, y = 0, and m = 2

    y = mx + b

    0 = 2(-7) +b

    0 = -14 + b

    14 = b

    b is the y-intercept, so your answer is 14

    the y intercept would be at (0,14)

    the m means how you move on the graph

    m=2 means 2/1

    you go up 2 and to the right one from your starting point

    which was (-7,0)

    0=2(-7)+b

    B=the y-intercept

    0=-14+b

    b=14
