Answer:
change in y: 0
change in x: 5
slope: 0
Explanation:
Sub these two points from Line E into the gradient formula (you can search this up on the internet) and you would get 0/5
Points: (1,3) and (6,3)
Rise over run
3-3 over 6-1
0/5 and the answer is 0
Generally, when it asks you to find the slope of a horizontal line, its always 0
