Answer:
Y=15x
Step-by-step explanation:
<h2>Okay so let's approach this problem!</h2><h2 />
X is books and Y is total cost
Let's find the slope!
Y2-Y1/ X2-X1
Just replace
![\frac{150 - 90}{10 - 6}](https://tex.z-dn.net/?f=%20%5Cfrac%7B150%20-%2090%7D%7B10%20-%206%7D%20)
![\frac{60}{4} = 15](https://tex.z-dn.net/?f=%20%5Cfrac%7B60%7D%7B4%7D%20%20%3D%2015)
The slope is 15
![y = 15x + b](https://tex.z-dn.net/?f=y%20%3D%2015x%20%2B%20b%20)
Now replace x and y with coordinates and solve
![150 = 15(10) + b \\ 150 = 150 + b \\ - 150 \\ 0 = b](https://tex.z-dn.net/?f=150%20%3D%2015%2810%29%20%2B%20b%20%5C%5C%20150%20%3D%20150%20%2B%20b%20%5C%5C%20%20-%20150%20%5C%5C%200%20%3D%20b)
The final equation:
y = 15x
