Question

# A ball thrown in space where there is virtually zero gravity would travel in a straight line at a constant speed. The data below was collected.$\begin{array}{c|c} \text{Time (s)} & \text{Distance (ft)} \\ \hline 10 & 5.70 \\ 0.2& 8.5 \\ 0.5& 16.6 \\ 0.7& 22.0 \\ 1.5& 43.6 \end{array}$Find an equation giving the distance traveled as a function of time.

We can use the two-point form formula to identify the line with two points which can be expressed by the equation:

\begin{aligned} \frac{y-y_1}{x-x_1}=\frac{y_2-y_1}{x_2-x_1} \end{aligned}
