Answer:

x = 4

Step-by-step explanation:

The inverse variation means that when y goes up by a factor of 20/5 = 4, the value of x goes down by the same factor.

x-intercepts are where the graph crosses the x-axis. These are (-1, 0) and (3, 0) from the graph.

y-intercepts are where the graph crosses the y-axis. This is (0, -3) from the graph.
