Answer:
![$ (y -y_1) = m(x - x_1) $](https://tex.z-dn.net/?f=%24%20%28y%20-y_1%29%20%3D%20m%28x%20-%20x_1%29%20%24)
Step-by-step explanation:
When a point and the slope of the line are given we use slope - one point form to determine the line of the equation.
Slope and One point form: y - y₁ = m(x - x₁)
where
is the point passing through the line and
is the slope of the line.
Point: (-2,2) Slope: ![$ \frac{-5}{2} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B-5%7D%7B2%7D%20%24)
∴ (x₁ ,y₁) = (-2,2) & m = ![$ \frac{-5}{2} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B-5%7D%7B2%7D%20%24)
Substituting we get:
y - 2 = ![$ \frac{-5}{2} (x + 2) $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B-5%7D%7B2%7D%20%28x%20%2B%202%29%20%24)
⇒ 2y - 4 = -5x - 10
⇒ 5x + 2y + 6 = 0
Point: (2,-3) Slope: ![$ \frac{-5}{2} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B-5%7D%7B2%7D%20%24)
y + 3 = ![$ \frac{-5}{2} (x - 2) $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B-5%7D%7B2%7D%20%28x%20-%202%29%20%24)
⇒ 2y + 6 = -5x + 10
⇒ 5x + 2y - 4 = 0
Point: (-9,7) Slope: ![$ \frac{4}{3} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B4%7D%7B3%7D%20%24)
y - 7 = ![$ \frac{4}{3} (x + 9) $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B4%7D%7B3%7D%20%28x%20%2B%209%29%20%24)
⇒ 3y - 21 = 4x + 36
⇒ 4x - 3y + 57 = 0
Point: (2,-7) Slope: ![$ \frac{-5}{2} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B-5%7D%7B2%7D%20%24)
y + 7 = ![$ \frac{-5}{2} (x - 2) $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B-5%7D%7B2%7D%20%28x%20-%202%29%20%24)
⇒ 2y + 14 = -5x + 10
⇒ 5x + 2y + 4 = 0
Point: (8,4) Slope: ![$ \frac{3}{4} $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B3%7D%7B4%7D%20%24)
y + 4 = ![$ \frac{3}{4} (x - 8) $](https://tex.z-dn.net/?f=%24%20%5Cfrac%7B3%7D%7B4%7D%20%28x%20-%208%29%20%24)
⇒ 4y + 16 = 3x - 24
⇒ 3x - 4y -40 = 0
Answer:
7 7/12
Step-by-step explanation:
Find the amount of rolls in all that were donated:
60 x 12 = 720.
The total amount used is 679. Subtract 679 from 720:
720 - 629 = 91.
Find the amount per dozen. Divide 91 with 12:
91/12 = 7 7/12
7 7/12 is your answer.
