Explanation:
Let's start with the y-intercept. (0, 50) is shifted 10 units to the right and becomes (10, 50). Next, we know the slope is 5. We can use this to plot more points, or we can use it to write an equation in point-slope form:
y - 50 = 5 (x - 10)
y - 50 = 5x - 50
y = 5x
So the new y-intercept is (0, 0).
What this means is that Jeremy's savings account will be worth $50 in ten years.
If we compare the new y-intercept to the old one, we see that the 10 unit shift to the right is the same as a 50 unit shift down. Shifting graph B up 50 units will bring us back to the original graph.
