Exploring Slope and Y-intercept of Linear Functions
- Anthony DiLaura
Explore the slope and y intercept of a linear function.
1. Drag the sliders and observe how the blue line changes. 2. Keep the b slider the same and describe what happens when you just change the m slider. 2a. Describe the difference in the lines slope when m = -2 compared to when m = 2. 2b. Describe the difference in the lines slope when m = 1/2 and when m = 6. 3. Describe what happens when you slide the b to be negative? positive? 4. Name two points that the blue line will pass through when the m = -2.5 and b = 2.
