Graph the system by using technology. what is the x-coordinate of the solution? round to the nearest hundredth. y=6x-7 y=2.2x+3

First we solve the equation for y.

Second we make a table for our x- and y-values. From the x values we determine our y-values.

Last we graph our matching x- and y-values and draw a line.

Example

We are going to graph the equation -4x+2y=2.

First we solve the equation for y:

Second we create our table:

x    y=2x+1
-2     -3
0      1
2      5
In the table above we have used our values for x to determine our matching values for y by exchanging the x in the equation for our given x-value.

As a last step we graph our points in the coordinate plane and connect them with a straight line.
