Answer:
B. -1
Step-by-step explanation:
You want the value of x corresponding to y = 6 as shown by the graph.
Coordinates
Locate the horizontal line at y = 6. Find where that intersects the plotted line, and determine the x-coordinate of that point.
The point where y = 6 is located half a grid square left of the y-axis. Each grid square is 2 units, so that is 1 unit left of the y-axis, or x = -1.
The approximate value of n for x = n at y = 6 is -1.
