Question

How do you plot positive and negative numbers on a coordinate plane horizontal and vertical

Answer 1

This is the coordinate plane shown below:

The horizontal axis is x-axis and the vertical axis is the y-axis.

See that the coordinate plane is broken down into 4 quadrants.

• Top Right - 1st quadrant

,

• Top Left - 2nd quadrant

,

• Bottom Left - 3rd quadrant

,

• Bottom Right - 4th quadrant

Now, we can plot a pair of point (x,y) on the coordinate plane.

We can have 4 types of points:

• (x positive, y positive) >>> falls in 1st quadrant

,

• (x negative, y positive) >>> falls in 2nd quadrant

,

• (x negative, y negative) >>> falls in 3rd quadrant

,

• (x positive, y negative) >>> falls in 4th quadrant

Let's plot 4 types of points in each coordinate and show in coordinate plane.

Let's plot:

A=(2,2)

B=(-2,2)

C=(-2,-2)

D=(2,-2)

In coordinate plane, they are:
