Discover Perpendicular Slopes
- Zach Schaver
1. Plot two points using tool. 2. Use the tool to create a line going through the two points. 3. Create a line perpendicular to the line you just created in step 2 using the tool. 4. Use the tool and click on both lines to find the slopes of both lines. 5. Finally, click on the algebra tab (looks like a calculator). In the input bar type in FractionText(m) to change the slope of the line from step 2 from a decimal to a fraction. Do the same for the perpendicular line, but use FractionText(m_1).
