### 1 App

App 1 - Finding the Point of Intersection: In this app, two lines may be manipulated to find where they have one solution, no solution, or infinite solutions.

Teaching Tip: As you drag the lines, the point of intersection is shown as a black dot on the grid. The nature of the solutions is shown in green at the lower right of the screen.
