The new coordinates
The new coordinate is calculated by:
![New = Old * k](https://tex.z-dn.net/?f=New%20%3D%20Old%20%2A%20k)
So, we have:
![A' = A * 2](https://tex.z-dn.net/?f=A%27%20%3D%20A%20%2A%202)
![A' = (-2,2) * 2](https://tex.z-dn.net/?f=A%27%20%3D%20%28-2%2C2%29%20%2A%202)
![A' = (-4,4)](https://tex.z-dn.net/?f=A%27%20%3D%20%28-4%2C4%29)
![B' = B * 2](https://tex.z-dn.net/?f=B%27%20%3D%20B%20%2A%202)
![B' = (1,3) * 2](https://tex.z-dn.net/?f=B%27%20%3D%20%281%2C3%29%20%2A%202)
![B' = (2,6)](https://tex.z-dn.net/?f=B%27%20%3D%20%282%2C6%29)
![C' = C * 2](https://tex.z-dn.net/?f=C%27%20%3D%20C%20%2A%202)
![C' = (1,0) * 2](https://tex.z-dn.net/?f=C%27%20%3D%20%281%2C0%29%20%2A%202)
![C' = (2,0)](https://tex.z-dn.net/?f=C%27%20%3D%20%282%2C0%29)
Y = 3
Explanation:
5y - 7 = 3y - 1
5y - 3y = - 1 + 7
2y = 6
y = 3
Answer:
y = ix + 6i + 4
Step-by-step explanation:
Since the line has undefined slope or indefinite slope we connote that the slope is (i)
Slope(m) of straight line = change in y ÷ change in x
Taking another point (x,y) on the line:
i = ![\frac{y - 4}{x - -6}](https://tex.z-dn.net/?f=%5Cfrac%7By%20-%204%7D%7Bx%20-%20-6%7D)
i = ![\frac{y - 4}{x + 6}](https://tex.z-dn.net/?f=%5Cfrac%7By%20-%204%7D%7Bx%20%2B%206%7D)
Cross multiplying gives;
y - 4 = ix + 6i
y = ix + 6i + 4
