Here, we will try to find the

**exact**height of a rice plant (remember, height is a continuous variable). Answer the questions below, in your notebook.**Question 1:**The units on the y-axis are in cm. From this, estimate the height of the rice plant. From now, to have a clear visualization, push "Show Height Line", to mark on the y-axis the height of the plant.

**Question 2:**Push "Zoom on Height" to get a more accurate measurement. Push it twice. Now, estimate the height of the rice plant. Is this the exact height?

**Question 3:**Zoom in a few more times to get more accurate. Estimate the height of the rice plant. Is this the exact height?

**Question 4:**Continue this process, to get an exact height. Did you arrive at a height?

**Note:**GeoGebra has difficulty with zooms, so if the red line disappears, push "Center on Line" to go back to the line.
