Evaluate the root.
Using the equation . Substitute for and for to get .
Move to the right side of the equation by subtracting from both sides of the equation.
Take the root of both sides of the to eliminate the exponent on the left side.
The complete solution is the result of both the positive and negative portions of the solution.
Evaluate the root.
The complete solution is the result of both the positive and negative portions of the solution.
First, use the positive value of the to find the first solution.
Next, use the negative value of the to find the second solution.
The complete solution is the result of both the positive and negative portions of the solution.
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 hyperbola is vertical or horizontal. If the slope is , the graph is horizontal. If the slope is undefined, the graph is vertical.
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.
