Alright, sweetheart. Your answer is C. I'm gonna tell you how so you can do it on your own from now on.
Step-by-step explanation:
Slope is the number of times you go up over the number of times you go over. This slope is a positive slope because up and right are both positive directions. Look at where the line crosses over on -3. Go up till you see where the line intersects again and then count the number of spaces you have to go over to get to the next intersection. I hope this helps.
