Answer: 5 lattes
Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.
Answer:
Given function:
![y=-x+3](https://tex.z-dn.net/?f=y%3D-x%2B3)
To graph the line using inputs -1,0,1 and 2.
Solution:
In order to find the points to be plot on graph we will plugin the input values as
in the given function.
1) When ![x=-1](https://tex.z-dn.net/?f=x%3D-1)
![y=-(-1)+3](https://tex.z-dn.net/?f=y%3D-%28-1%29%2B3)
![y=1+3](https://tex.z-dn.net/?f=y%3D1%2B3)
![y=4](https://tex.z-dn.net/?f=y%3D4)
Point (-1,4)
2) When ![x=0](https://tex.z-dn.net/?f=x%3D0)
![y=-(0)+3](https://tex.z-dn.net/?f=y%3D-%280%29%2B3)
![y=0+3](https://tex.z-dn.net/?f=y%3D0%2B3)
![y=3](https://tex.z-dn.net/?f=y%3D3)
Point (0,3)
3) When ![x=1](https://tex.z-dn.net/?f=x%3D1)
![y=-(1)+3](https://tex.z-dn.net/?f=y%3D-%281%29%2B3)
![y=-1+3](https://tex.z-dn.net/?f=y%3D-1%2B3)
![y=2](https://tex.z-dn.net/?f=y%3D2)
Point (1,2)
4) When ![x=2](https://tex.z-dn.net/?f=x%3D2)
![y=-(2)+3](https://tex.z-dn.net/?f=y%3D-%282%29%2B3)
![y=-2+3](https://tex.z-dn.net/?f=y%3D-2%2B3)
![y=1](https://tex.z-dn.net/?f=y%3D1)
Point (2,1)
The points to be plot in the graph are:
(-1,4),(0,3),(1,2),(2,1)
