Answer 1

Given:

The equation is:

`y=2x+1`

To find:

The y-coordinates for the ordered pairs (0, _), (-1, _) and (1, _)for this equation.

Solution:

We have,

`y=2x+1`

For
`x=0`,

`y=2(0)+1`

`y=0+1`

`y=1`

For
`x=-1`,

`y=2(-1)+1`

`y=-2+1`

`y=-1`

For
`x=1`,

`y=2(1)+1`

`y=2+1`

`y=3`

Therefore, the complete ordered pairs are (0,1), (-1, -1) and (1,3). Plot these points on a coordinates plane and connect them by a straight line as shown in the below figure.
