Answer 3

It depends.
First, what is the data? It should be a list of points: example:
(time, distance traveled),
If the points fall exactly on a line, you would pick two points, and find the equation of a line.
One way: find the slope between the 2 points, then use y= mx + b, and one of the points to find b.

Answer 4

If the data is "roughly" a line, but scattered, then you use a
"least-squares" fitted line. This is a more complicated process.

Answer 5

This question was asking in general, its for a study guide.

Thanks though.
