Find the slope of the lines as fractions

The general formula to get the slope of the line is:


Question (7):
We are given the points:
(-1,-11) representing (x1,y1)
(16,-8) representing (x2,y2)
using the above formula, we can get the slope as follows:


 

Question (8):
We are given the points:
(-14,10) representing (x1,y1)
(-3,15) representing (x2,y2)
using the above formula, we can get the slope as follows:


 

Question (9):
We are given the points:
(-17,-19) representing (x1,y1)
(-7,-5) representing (x2,y2)
using the above formula, we can get the slope as follows:
