Hello can you plz do this in English so I can help
Answer:

Step-by-step explanation:
We find slope by; change in y ÷ change in x,
Change in y = -4 - 3 = -7
Change in x = 7 - - 2 = 9
Slope of line MN = -7 ÷ 9 = 
Well remember this:
When the signs are the same it is positive
When the signs are different make it negative
When you are subtracting a negative and positive, it is going to be like adding
for example:
-9 - 5 = -14
You just add 9 and 5 to get 14, the signs are different so it is going to be negative. ONLY WHEN YOU ARE SUBTRACTING NEGATIVES
