The answer is A. Parallel lines have the same slope, which is 1/2 in this problem. The equation of the line in A matches the slope of 1/2 and also passes through (-8,0). You can check that it does by substituting the x and y values in the equation, like this: 0 = 1/2(-8) + 4 0 = -4 +4 0 = 0 which checks!
