We are given the equation of a line
y = -2x + 1
We have to find the value of y at three different values of x i.e. at x =0, -3 and 1
In order to find the value of y at any given x, simply replace x by that number.
So, for x=0, we will replace x by 0 to find the value of y. So y will be:
y = -2(0) + 1
y = 1
This can be expressed as an ordered pair as (0,1)
Similarly for x=-3, we get:
y = -2(-3) + 1 = 6 + 1
y = 7
This can be expressed as an ordered pair as (-3, 7)
And, finally for x=1, we get:
y= -2(1) + 1 = -2 + 1
y= -1
This can be expressed as an ordered pair as (-1, -1)
y = -2x + 1

Answer:
[tex]y=-1[/tex]
Step-by-step explanation:
We have been given an equation [tex]y=-2x+1[/tex]. We are asked to complete the given table using our given equation.
We can see that our given table has two columns namely x and y.
To find the value of y for given values of x, we need to substitute the given x value in our equation.
Substituting [tex]x=0[/tex] in our equation we will get,
[tex]y=-2*0+1[/tex]
[tex]y=0+1[/tex]
[tex]y=1[/tex]
Therefore, the value of y for first row is 1 and ordered pair will be (0,1).
Substituting [tex]x=-3[/tex] in our equation we will get,
[tex]y=-2*-3+1[/tex]
[tex]y=6+1[/tex]
[tex]y=7[/tex]
Therefore, the value of y for 2nd row is 7 and ordered pair will be (-3,7).
Substituting [tex]x=1[/tex] in our equation we will get,
[tex]y=-2*1+1[/tex]
[tex]y=-2+1[/tex]
[tex]y=-1[/tex]
Therefore, the value of y for 3rd row is [tex]-1[/tex] and ordered pair will be (1,-1).
