Hello!
First of all you look at how many X's the line moves by, in this case it is -3
Then you look at how many y's the line moves by, in this case it is -2
Then you add together the number of X's moved and the number of y's moved:
-3x + -2y
( adding a negative number is the same as subtracting that number)
thus the answer is A. -3x-2y
Hope This helps! :)
