Let's start by understanding that the graph is a linear line. We have a common difference if 4.5 for every 10x we have more.
We can start by finding the gradient, using rise over run. Let's take (10, 4.5) and (20, 9)
Our rise is 9 - 4.5 = 4.5 and our run is 10. Then, our gradient becomes 4.5/10 = 0.45
Now, we can substitute points using the point-slope form.
y - 4.5 = 0.45(x - 10)
y - 4.5 = 0.45x - 4.5
Hence, our line becomes y = 0.45x and you can verify by substituting in points from the table.
Answer:
8 books
Step-by-step explanation:
- The answer is 8 because you add up all of the bars which get you to 40
- Finally you divide 40 by the number of bars which gets you 5. 40/5=8
- Hope this helped :)

Answer:
23/2
Step-by-step explanation:
first turn the mixed number into a fraction:
2*10=20
20+3=23
so, we get 23/2
