Given:
The equation is:
[tex]y=2x+1[/tex]
To find:
The y-coordinates for the ordered pairs (0, _), (-1, _) and (1, _)for this equation.
Solution:
We have,
[tex]y=2x+1[/tex]
For [tex]x=0[/tex],
[tex]y=2(0)+1[/tex]
[tex]y=0+1[/tex]
[tex]y=1[/tex]
For [tex]x=-1[/tex],
[tex]y=2(-1)+1[/tex]
[tex]y=-2+1[/tex]
[tex]y=-1[/tex]
For [tex]x=1[/tex],
[tex]y=2(1)+1[/tex]
[tex]y=2+1[/tex]
[tex]y=3[/tex]
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.
