    Answer:

    [see explanation and graphs]

    Step-by-step explanation:

    Going by the slope, which is 5/2, your y-intercept would be 4.

    m=\frac{64-44}{24-16} =\frac{20}{8} =\frac{5}{2}

    Answer:

    4

    Step-by-step explanation:

    find the equation of the line:

    slope = rise / run

    rise is 20, run is 8

    20/8 = 5/2

    slope intercept form is y = mx + b

    where m is slope and b is y int

    y = 5/2(x) + b

    use a point given to find b

    44 = 5/2(16) + b

    44 = 40 + b

    b = 4
