[NOW PLEASE!!!]First, a graph of f(x) = 2x + 1 is drawn. Then, three graphs of 2(x + k) + 1 are drawn, for k = 1, 2, 3. Which will be true of these three graphs?

A. Their slopes will be the same as the slope of f(x), and their x-intercepts will be to the right of the x-intercept of f(x).
B. Their slopes will be the same as the slope of f(x), and their x-intercepts will be to the left of the x-intercept of f(x).
C. Their slopes will be different from the slope of f(x), and their x-intercepts will be to the right of the x-intercept of f(x).
D. Their slopes will be different from the slope of f(x), and their x-intercepts will be to the left of the x-intercept of f(x).
