Do you know how to find the minor axis on a graph?

anonymous · Answer

no

anonymous · Answer

Okay, so the minor axis is essentially the distance between two points. For your problem you need to find the distance between the points (-4, -5) and (-4, 7). The distance is your minor axis. The distance is 12. So your answer is 12.

If you curious, here's the graph. The points are taken off the shorter lengths from the center. the longer side would be the major axis.
