You could graph this, but it is simpler in this case to do it mathematically.
Since the x and values are the same (implying undefined slope) you can subtract the smaller y value from the larger y value. 2.5-1.2=1.3.
Let, the first number = C
second number will be = C + 2 ['cause next will be odd so we can't include that]
Third number = C + 4
Now, their sum would be:
C + C+2 + C+4 = 3C + 6
In short, Your Answer would be 3C + 6
Hope this helps!
Answer: -2
(-5)(-1)x=(10)(-1)
5x = -10
x = -2
(X-4, y-9) since it moves left its negative and the y went down makes that negative too
