16, add 16 to 8 and then the rest is simple
Use the slope form:
m= (y2-y1)/(x2-x1)
Plug in two sets of points from table 4. (0,9) (2,4)
m= (4-9)/(2-0)
m= -5/2 or -2.5
Do the same for the second table. I can't see it very well, so I am assuming that number under 1 is 5. (0,3) and (1,5)
m= (y2-y1)/(x2-x1)
m= (5-3)/(1-0)
m= 2/1 or 2
I hope this helps!

Answer:
60%
Step-by-step explanation:
25-10=15 non-fiction books
15/25=.6
.6=60%
It is given in the statement that the increase in number of scones is same from Robbie till Charlie.
Let us assume that Robbie buy x scones and every boy buys y more scones than the previous ones.
The number of scones for each of the boy can be written as:
Robbie = x
Cameron = x + y
Louis = x + 2y
Tom = x + 3y
Charlie = x + 4y
Total number of scones = 60
So,
Robbie and Cameron's combined total number of scones is three sevenths of the total of Louis, Tom and Charlie. Mathematically this can be stated as:
Using Solving the two equations simultaneously:
This means, Robbie buys 8 scones,
Cameron buys 8 + 2 = 10 scones,
Louis buys 8 + 4 = 12 scones,
Tom buys 8 + 6 = 14 scones,
and Charlie buys 8 + 8 = 16 scones
