Answer: y=9
Step-by-step explanation:
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)
