The answer is -3021/50 - 34x
Answer:
A = -1
So, option (B) is the correct answer.
Step-by-step explanation:
The two points on line have coordinates: p (x₁, y₁) = (0, A) and q(x₂, y₂) = (2 , -3)
Slope of line = A
Slope of line = ![\frac{y_{2} - y_{1}}{x_{2} -x_{1}}](https://tex.z-dn.net/?f=%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%7D%7Bx_%7B2%7D%20-x_%7B1%7D%7D)
Now since the slope of line is A and its has two coordinates (0, A) and (2 , -3), ∴
![A = \frac{y_{2} - y_{1}}{x_{2} -x_{1}}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7By_%7B2%7D%20-%20y_%7B1%7D%7D%7Bx_%7B2%7D%20-x_%7B1%7D%7D)
![A = \frac{-3 - A}{2 - 0}](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B-3%20-%20A%7D%7B2%20-%200%7D)
![2A = -3 - A](https://tex.z-dn.net/?f=2A%20%3D%20-3%20-%20A)
![2A + A = -3](https://tex.z-dn.net/?f=2A%20%2B%20A%20%3D%20-3)
![3A = -3](https://tex.z-dn.net/?f=3A%20%3D%20-3)
![A = -1](https://tex.z-dn.net/?f=A%20%3D%20-1)
So, option (B) is the correct answer.
