We know how to read and plot coordinates on a **coordinate grid** with *positive* numbers.

Now we extend the grid in all directions to include *negative*** **numbers.

Look carefully at how the axes are numbered.

Look at the point **A**.

Its** x-coordinate is -5** on the x-axis.

Its** y-coordinate is -3 **on the y-axis.

Remember** ****the x number**

**comes**

*before*the y*number*

**.****A** has coordinates **(-5, -3)**.

Look at the coordinates of all four points of the parallelogram, shown below.

Remember to read **the** **x** ** before the y**.
