Point Slope Discovery App
Drag the sliders to observe what happens when you change the x value, the y value, and the slope (m).
The x value in the point is represented by the blue slider. The y value of the point is represented by the pink slider. The slope - the rate of change between two points on the line - is represented by the red slider.
What happens to the line when you make the x value larger? What happens in the equation?
What happens to the line when you make the x value smaller? What happens in the equation when you make the x value negative?
What happens to the line when you make the y value smaller? What happens in the equation?
What happens to the line when you make the y value larger? What happens in the equation when you make the y value negative?
