Can someone assist me with these? Graphing on geogebra or demos is preferred with a screenshot.

Investigative Task: Time and Speed An object is dropped from a height and its speed is measured after fixed times. Because of the difficulty of measuring speeds, some of the data may not be perfectly correct, but without more accurate measuring devices, we are stuck with these values. So here is observational data on the speed of a ball dropped from a certain height at various times. (Set your calc to two decimal places for accuracy) Time (sec) 0 0.2 0.4 0.6 0.8 Speed 1.94 3.55 6.03 7.97 (m/sec) Put the data above in your calculator and answer the following 1. Is there an explanatory-response relationship? If so, what is the explanatory variable and what is the response variable? (2 pts) 2. Describe the relationship in terms of form, direction, and strength. (3 points) 3. Find the equation of the least squares regression line for this data set. (2 points) 4. Find the correlation coefficient r and explain what its value tells you in words. (2 points) E
