In this case, 
Therefore,

The slope is negative as it slopes to the left
using the extremities of the line:-
-(10+10 / (10 + 10) = -1
slope is -1.
Answer:
false
Step-by-step explanation:
we study proofs in computing because it helps us to understand the mathematical computation. With the help of proofs in computing it is very easy to understand all the mathematical computation but in given statement it is given that it helps us to understand data structure so it is a false statement.
