No, because if you subtract 2.5 from 1.5, you get negative 1.
The slope of a line can be found with any two points on the line:
slope=(y2-y1)/(x2-x1) where (x1,y1) and (x2,y2) are any two points...
slope=(25-17)/(7-3)
slope=8/4
slope=2
So, we need to consider what is being done.
So, lets start with the -3.
-3*
Now, lets see what's next
2 times a number is the same as saying 2x, then add one.
That is equal to five.
-3(-2x+1)=5
Now,
6x-3 = 5
6x = 8
x= 8/6
Answer:
the pattern is +2, +6, +10, +14, +18 etc
so its in increment of 4
the rest is trivial
