Answer 1

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. 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)

Answer 2

Answer:

When x = 1 , we get, y = -1      

Step-by-step explanation:

Given:   Linear equation y = - 2x + 1

We have to complete the table so that each line of table for the values of x and y form the ordered pair of x and y.

Consider the given linear equation y = -2x + 1

Since, by putting different values of x , we can get values of y .

Here, when we put x = 1

We get,

y = -2 (1) + 1

Simplify, we get,

y = -2 + 1 = -1

thus, when x = 1 , we get, y = -1
