Answer:
 The slope of the line that contains the points R(0, 4) , S(5, 0) is  .
 .
Step-by-step explanation:
Formula 
The slope of the line is defined as 

As given in the question 
The line contains the points  R(0, 4), S(5, 0) . 




Put all the points in the formula 


Therefore the slope of the line that contains the points R(0, 4) , S(5, 0) is  .
