Answer:
gives ![y_2 - y_1 = 4](https://tex.z-dn.net/?f=y_2%20-%20y_1%20%3D%204)
Step-by-step explanation:
Given
![y = 4x](https://tex.z-dn.net/?f=y%20%3D%204x)
![(x_1,x_2) = (x,x+1)](https://tex.z-dn.net/?f=%28x_1%2Cx_2%29%20%3D%20%28x%2Cx%2B1%29)
Required
Show that the y values increases by 4 for ![x_2 - x_1 = 1](https://tex.z-dn.net/?f=x_2%20-%20x_1%20%3D%201)
We have:
![y = 4x](https://tex.z-dn.net/?f=y%20%3D%204x)
For ![x_1 = x](https://tex.z-dn.net/?f=x_1%20%3D%20x)
![y_1 = 4x_1](https://tex.z-dn.net/?f=y_1%20%3D%204x_1)
Substitute ![x_1 = x](https://tex.z-dn.net/?f=x_1%20%3D%20x)
![y_1 = 4x](https://tex.z-dn.net/?f=y_1%20%3D%204x)
For ![x_2 = x + 1](https://tex.z-dn.net/?f=x_2%20%3D%20x%20%2B%201)
![y_2 = 4x_2](https://tex.z-dn.net/?f=y_2%20%3D%204x_2)
Substitute ![x_2 = x + 1](https://tex.z-dn.net/?f=x_2%20%3D%20x%20%2B%201)
![y_2 = 4(x+1)](https://tex.z-dn.net/?f=y_2%20%3D%204%28x%2B1%29)
![y_2 = 4x+4](https://tex.z-dn.net/?f=y_2%20%3D%204x%2B4)
So, we have:
![y_2 = 4x+4](https://tex.z-dn.net/?f=y_2%20%3D%204x%2B4)
![y_1 = 4x](https://tex.z-dn.net/?f=y_1%20%3D%204x)
Subtract
from ![y_2](https://tex.z-dn.net/?f=y_2)
![y_2 - y_1 = 4x + 4 - 4x](https://tex.z-dn.net/?f=y_2%20-%20y_1%20%3D%204x%20%2B%204%20-%204x)
Collect like terms
![y_2 - y_1 = 4x - 4x+ 4](https://tex.z-dn.net/?f=y_2%20-%20y_1%20%3D%204x%20-%204x%2B%204)
![y_2 - y_1 = 4](https://tex.z-dn.net/?f=y_2%20-%20y_1%20%3D%204)
Hence:
gives ![y_2 - y_1 = 4](https://tex.z-dn.net/?f=y_2%20-%20y_1%20%3D%204)
i.e. an increment of 4
