Tangent Line applet

Using this Geogebra applet, you will be able to view the slope, y-intercept, and the equation of the tangent line. Drag the h slider to increase/decrease the horizontal distance between points A and B to determine how he effects the rest of the graph. Use the graph and slider to answer the questions.

Question 1

if h=2.26, and B(0,0), what are the coordinates of A? (answer as (x, y)

Question 2

What happens to the polygon if you increase the h slider?

Question 3

Move point A on the curve. which side of the triangle stays the same? What is the length of this side?
