Question

For the equation y = 2x – 3, complete the table for the given values of x. Using the information from the table, graph the line of the equations on the coordinate plane below. Be sure to plot all points from the table and draw a line connecting the points.

Answer 1

We complete the table as follows:

*We replace the values stated in x [In the table] and solve for y:

*x = -1:

`y=2(-1)-3\Rightarrow y=-5`

So, the value for y when x = -1 is -5.

*x = 1:

`y=2(1)-3\Rightarrow y=-1`

The value for y when x = 1 is -1.

*x = 3:

`y=2(3)-3\Rightarrow y=3`

The value for y when x = 3 is 3.

*** The table will look something like:

x | y

-1 | -5

1 | -1

3 | 3
