is a distance, which means it should be a positive number.
The slope of the line between the focus and the center determines whether the ellipse is vertical or horizontal. If the slope is , the graph is horizontal. If the slope is undefined, the graph is vertical.
Tap for more steps…
Slope is equal to the change in over the change in , or rise over run.
The change in is equal to the difference in x-coordinates (also called run), and the change in is equal to the difference in y-coordinates (also called rise).
Substitute in the values of and into the equation to find the slope.
