The position of a particle moving to the right on the x-axis is given by x(t), where x(t) is measured in centimeters and t is measured in seconds for 0≤t≤50. If y=x(t) is a linear function, which of the following would most likely give the best estimate of the speed of the particle, in centimeters per second, at time t=10 seconds?

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
