The answer is
A. Set X has 10 possible groupings.
C. Set Y = {ABC, ABD, ABE, ACD, ACE, ADE}

Good luck :)
Answer:
![y - x = 2](https://tex.z-dn.net/?f=y%20-%20x%20%3D%202)
Step-by-step explanation:
Given
Points (-2,0) and (-3,-1)
Required
Equation of Line
The first step is to determine the slope of the line; using the following formula
![m = \frac{y_2 - y_1}{x_2 - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%20y_1%7D%7Bx_2%20-%20x_1%7D)
![Where\ (x_1,y_1) = (-2,0)\ and\ (x_2,y_2) = (-3,-1)](https://tex.z-dn.net/?f=Where%5C%20%28x_1%2Cy_1%29%20%3D%20%28-2%2C0%29%5C%20and%5C%20%28x_2%2Cy_2%29%20%3D%20%28-3%2C-1%29)
becomes
![m = \frac{-1 -0}{-3 - (-2)}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-1%20-0%7D%7B-3%20-%20%28-2%29%7D)
![m = \frac{-1}{-3 +2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-1%7D%7B-3%20%2B2%7D)
![m = \frac{-1}{-1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7B-1%7D%7B-1%7D)
![m = 1](https://tex.z-dn.net/?f=m%20%3D%201)
The next is to determine the equation of the line using any of the points
The formula is as thus;
![m = \frac{y - y_1}{x - x_1}\ or\ m = \frac{y - y_2}{x - x_2}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By%20-%20y_1%7D%7Bx%20-%20x_1%7D%5C%20or%5C%20%20m%20%3D%20%5Cfrac%7By%20-%20y_2%7D%7Bx%20-%20x_2%7D)
Using ![m = \frac{y - y_1}{x - x_1}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By%20-%20y_1%7D%7Bx%20-%20x_1%7D)
![Where\ (x_1,y_1) = (-2,0)\ and\ m =1](https://tex.z-dn.net/?f=Where%5C%20%28x_1%2Cy_1%29%20%3D%20%28-2%2C0%29%5C%20and%5C%20m%20%3D1)
![1 = \frac{y-0}{x - (-2)}](https://tex.z-dn.net/?f=1%20%20%3D%20%5Cfrac%7By-0%7D%7Bx%20-%20%28-2%29%7D)
![1 = \frac{y-0}{x +2}](https://tex.z-dn.net/?f=1%20%20%3D%20%5Cfrac%7By-0%7D%7Bx%20%2B2%7D)
![1 = \frac{y}{x +2}](https://tex.z-dn.net/?f=1%20%20%3D%20%5Cfrac%7By%7D%7Bx%20%2B2%7D)
Multiply both sides by x + 2
![(x+2)*1 = \frac{y}{x +2} * (x+2)](https://tex.z-dn.net/?f=%28x%2B2%29%2A1%20%20%3D%20%5Cfrac%7By%7D%7Bx%20%2B2%7D%20%2A%20%28x%2B2%29)
![(x+2)*1 = y](https://tex.z-dn.net/?f=%28x%2B2%29%2A1%20%20%3D%20y)
![x+2 = y](https://tex.z-dn.net/?f=x%2B2%20%20%3D%20y)
![y = x + 2](https://tex.z-dn.net/?f=y%20%3D%20x%20%2B%202)
Subtract x from both sides
![y - x = x - x +2](https://tex.z-dn.net/?f=y%20-%20x%20%3D%20x%20-%20x%20%2B2)
![y - x = 2](https://tex.z-dn.net/?f=y%20-%20x%20%3D%202)
Hence, the equation of the line in standard form is ![y - x = 2](https://tex.z-dn.net/?f=y%20-%20x%20%3D%202)

2/3 + 3/4 + 5/8......common denominator is 24
16/24 + 18/24 + 15/24 = 49/24 (or 2 1/24)
