Answer:
The GCF of 100 and 16 is 4
When you have a linear equation of the form y = mx, such as this one, you know immediately that the line passes thru the origin (0,0). Were the form y = mx + b, then the y-intercept would be (0,b) and the x-intercept ( [-b/m, 0).

Answer: see image attached
y<x/2+6 is the yellowish area (with dashed boundary as that does not belong to the solution space)
x+3y>=12 is rearranged as y>=-x/3+4 and solutions correspond to the bluish shaded area (with solid line, due to the equal sign)
The solutions satisfying both inequalities are in the overlap area of the two.
The first equation gives:
y = 2 * (x + 3) >>> y = 2x + 6
Or
2x - y = -6
The second sentence gives:
y = 5 + 3x >>> 3x - y = -5
The answer is (A), the first choice.
