Answer:

Step-by-step explanation:

Since the inequality is < then the line separating the shaded and plain regions will be broken.

Thus graph A or B

Choose a test point in each shaded region and check validity of solution

From A choose (0, 2), then

2 < 0 + $\frac{4}{7}$ → 2 < $\frac{4}{7}$ ← False

From B choose (0, - 2), then

- 2 < 0 + $\frac{4}{7}$ → - 2 < $\frac{4}{7}$ ← True

Thus the graph representing the inequality is B
