The rate of change of coordinates is what is called slope. Based on the given question, you are to find the slope and the slope is expressed as;

m = y2-y1/x2-x1

Given the coordinates (-1,3) and (-4,8)​

x1 = -1, y1 = 3, x2 = -4 and y2 = 8

Substitute the values into the slope formula as shown;

m = 8-3/-4-(-1)

m = 5/-4+1

m = 5/-3

Hence the rate of change of the points (-1,3) and (-4,8)​ is -5/3
