Newton's Second law of motion is
F = m * a ( force = mass * acceleration).
So if a is constant then a = F 1 / m1 and a = F2 / m2 then
F1 /m1 = F2 / m2 and if m1 > m2 then
F1 must be greater than F2.
Answer is C.
Whether a line is "steep" or "shallow" depends on the slope of the line. In the equation y=mx+b, m is the slope. In your first equation, 1/2x+4, the slope would be 1/2 which means there is 1 increase in the vertical, or y, value for each 2 increases in the horizontal, or x value. This line would be shallow.
