  1. The slope of the line is (7-4)/(5-1)= 0.75

    The equation of the line is
    (y-4)/(x-1) = slope = 0.75

    y = 0.75 x + 3.25
    ==============
    There are other ways to do it. You could write down the standard form y = mx + b and substitute the two pairs of (x,y) numbers,

    4 = m + b
    7 = 5m + b
    and then solve for m and b.
