The Function Editor App

How do I solve a system of equations with graphs?

To solve a system of equations with graphs, follow these steps.

Enter the equations given in the example into the function editor space.

Example:

\( y = \frac{1}{3}x - 2 \)

\( y = -x^2 + 8 \)

1.    Press a Ã

2.    Press the down arrow key ≥ to select 5: Intersection

3.    Move the cursor by pressing the arrow keys. Alternatively type the x-value close to the point of intersection that you want to compute and press =.
