Introduction to the Point-Slope Equation
Use the slider to change the slope. Drag point P to see what happens to the equation.
Move the slider to see the slope of the line change. Set the slope at 2.5. Drag point P to (5,7): Record the equation. Drag and record for points (11,4), (-6,8), (3,-4). How does the point affect the equation? Move the point to get the equation to be: y-6=-2(x-10) Move the point to get the equation to be: y-3=0.5(x+4)
