Okay it’s the right answer
Let the unknown number be x
13x+72= -23x
13x+23x= -72
36x= -72
x= -2
The answer is 2,500
32,000 - 24,500 /3
Answer:
slope is 3
Step-by-step explanation:
Slope = 
change in y = (13-7), (19-13), (25-19), (31-25)
change in y = 6
Change in x = (4-2), (6-4), (8-6), (10-8)
Change in x = 2
Therefore slope = 
Slope = 3
