Question

Complete these ordered pairs for this equation. (0, ), (-1,), (1, ) y=2x+1 Helpp

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.
