Let's list out what we already know:
Alexa's book is into 8 chapters
Rose's book is into 6 chapters
So since they are out of how many chapters, they number of chapters their books are split into will be the denominator of each fraction. Each girl has already read 3 chapters, so they'll have 3 as their numerator.
Alexa: 3/8
Rose:3/6
We can see that Rose is already at half of the book while Alexa's half would be 4/8, and she isn't there yet. So Rose read more of her book.
Answer:
![y = 2x -4](https://tex.z-dn.net/?f=y%20%3D%202x%20-4)
Step-by-step explanation:
Slope intercept form is
where <em>m </em>is the slope and <em>b </em>is the y-intercept.
Slope is
or
in this case = ![\frac{0 - (-4)}{2 - 0} = \frac{4}{2} = 2](https://tex.z-dn.net/?f=%5Cfrac%7B0%20-%20%28-4%29%7D%7B2%20-%200%7D%20%3D%20%5Cfrac%7B4%7D%7B2%7D%20%3D%202)
Substitute one of the coordinates for x and y. I am going to use (0, -4) so:
![-4 = 2(0) + b\\-4 = 0 + b\\-4 = b](https://tex.z-dn.net/?f=-4%20%3D%202%280%29%20%2B%20b%5C%5C-4%20%3D%200%20%2B%20b%5C%5C-4%20%3D%20b)
since m = 2 and b = -4, we can conclude that the equation would be
![y = 2x -4](https://tex.z-dn.net/?f=y%20%3D%202x%20-4)
