Question

If a linear function has the points ​(0​,1​) and ​(5​,8​) on its​ graph, what is the rate of change of the​ function?

Select the correct choice below​ and, if​ necessary, fill in the answer box to complete your choice.
A.
The rate of change is ( ) ​(Type an integer or a simplified​ fraction.)
B.
There is no solution.

Answer 1

A. 7/4
Rate of change is the same as slope, it is how the line has to go to get from the first to the second point. The slope function is y2-y1 / x2-x1. So we end up with 8-1/5-1 making 7/4
