A.
The rate of change is ( ) ​(Type an integer or a simplified​ fraction.)
B.
There is no solution.

Respuesta :

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
