Question

Graph the function y=-x+3 using inputs of -1,0,1, and 2

Answer 1

Given function:

`y=-x+3`

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
`x` in the given function.

1) When
`x=-1`

`y=-(-1)+3`

`y=1+3`

`y=4`

Point (-1,4)

2) When
`x=0`

`y=-(0)+3`

`y=0+3`

`y=3`

Point (0,3)

3) When
`x=1`

`y=-(1)+3`

`y=-1+3`

`y=2`

Point (1,2)

4) When
`x=2`

`y=-(2)+3`

`y=-2+3`

`y=1`

Point (2,1)

The points to be plot in the graph are:

(-1,4),(0,3),(1,2),(2,1)
