we first substitute the x
y= -2(-2-1)
=6
and then use a calculator to do the sum
which gives us 6
y= -2(-1-1)
= 4
y= -2(0-1)
=2
y= -2(1-1)
=0
y= -2(2-1)
=-2

Answer:
(b)
Step-by-step explanation:
Given
![8x + 3y = 24](https://tex.z-dn.net/?f=8x%20%2B%203y%20%3D%2024)
Required
The graph
First, make y the subject
![3y = 24 - 8x](https://tex.z-dn.net/?f=3y%20%3D%2024%20-%208x)
Divide through by 3
![y = 8 - \frac{8}{3}x](https://tex.z-dn.net/?f=y%20%3D%208%20-%20%5Cfrac%7B8%7D%7B3%7Dx)
Let x = 3
![y = 8 - \frac{8}{3}*3 = 8 - 8 = 0](https://tex.z-dn.net/?f=y%20%3D%208%20-%20%5Cfrac%7B8%7D%7B3%7D%2A3%20%3D%208%20-%208%20%3D%200)
Let x = 6
![y = 8 - \frac{8}{3}*6 = 8 - 16 = -8](https://tex.z-dn.net/?f=y%20%3D%208%20-%20%5Cfrac%7B8%7D%7B3%7D%2A6%20%3D%208%20-%2016%20%3D%20-8)
So, we plot the graph through
and ![(6,-8)](https://tex.z-dn.net/?f=%286%2C-8%29)
