Ok. Type the values in your graphing calculator. Go to Stat-Edit and then TYPE IN
THE VALUES. Next, hit linear regression to find the equation.
Y=ax+b
Y=-8.5x+99.2
The Y-Intercept means that when there are 0 knots, the rope will be 99.2(cm).
Slope is -8.5 and it represents a negative relationship between the length of the rope and the # of knots.
