| Strategy | How to execute in Desmos | | :--- | :--- | | | Type the equation. Look for the ( x )-intercept (where line hits zero). | | Solve systems of equations | Graph both equations. Click on the intersection point to see ( (x,y) ). | | Find min/max of a parabola | Graph the quadratic. Click on the vertex. | | Regression (Line of best fit) | Input data points as a table. Use ( y_1 \sim mx_1 + b ). | | Check equivalent expressions | Graph the original and your answer. If the lines overlap entirely, they are equivalent. | sat math guide
