**Coordinate Grid & Plotting Points**

**The Coordinate Plane**

What does it look like and why do we need it?

Pilots & Navigators

Any job that navigates anywhere uses a coordinate plane to help it find their location and distance to their destination.

Engineers

An engineer needs the coordinate plane to calculate where a machine or structure needs to be reinforced.

X & Y Axis

X-Axis: The horizontal (left to right) axis of the graph.

Y-Axis: The vertical (up and down) axis of the graph.

Who uses Coordinate Planes/Grids?

Can you name jobs that you think uses this area of math?

Let's Look, Listen & Learn :)

Economists and accountants use business models, they use graphs to show past, present, and future data.

The Coordinate Plane/Grid:

A plane (2D surface) containing

2 perpendicular axes (x and y) intersecting at a point called the origin (0,0).

Vocabulary

The Origin is the point of intersection of the x and y axis on a coordinate plane.

Origin

Quadrants - Any quarter of a plane divided by an x and y axis.

There are 4 quadrants on a coordinate plane.

Quadrants

A pair of numbers where order is important, often

used to indicate a point on a coordinate plane/grid.

The first # is the horizontal position, and the second # is the vertical position. (x,y)

Ordered Pair
