Answer:
The line passes through (1,2) and (4,4)
The equation,
![\frac{y - y1}{x - x1} = \frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%20-%20y1%7D%7Bx%20-%20x1%7D%20%20%3D%20%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
![\frac{y - 2}{x - 1} = \frac{4 - 2}{4 - 1} = \frac{2}{3}](https://tex.z-dn.net/?f=%20%5Cfrac%7By%20-%202%7D%7Bx%20-%201%7D%20%20%3D%20%20%5Cfrac%7B4%20-%202%7D%7B4%20-%201%7D%20%20%3D%20%20%5Cfrac%7B2%7D%7B3%7D%20)
![3(y - 2) = 2(x - 1)](https://tex.z-dn.net/?f=3%28y%20-%202%29%20%3D%202%28x%20-%201%29)
![= > 3y - 6 = 2x - 2](https://tex.z-dn.net/?f=%20%3D%20%20%3E%203y%20-%206%20%3D%202x%20-%202)
![= > 2x - 3y - 2 + 6 = 0](https://tex.z-dn.net/?f=%20%3D%20%20%3E%202x%20-%203y%20-%202%20%2B%206%20%3D%200)
![= > 2x - 3y + 4 = 0](https://tex.z-dn.net/?f=%20%3D%20%20%3E%202x%20-%203y%20%2B%204%20%3D%200)
Answer:
I believe it is 60-10=x because it says she purchased it with 60$ but recieved 10$ in change causing the amount we dont know to be a variable such as "x"
Step-by-step explanation:
It would be the third equation.
4 balls for children plus the 5 balls for herself plus the accessories for 9.45 all together is 28.71.
Subtract the 9.45 from the total cost then divide by 9 to get the cost per ball
C1s1 c1s2
c2s1 c2s2
c3s1 c3s2
c4s1 c4s2
altogether 8,
or you can find it 4(colors)*2(styles)=8
