If your name is not on this list you need to go to study island and complete 10 questions on Ratios.

Coordinate Grid Practice Plot the following points:

Coordinate Grid Practice What are the coordinates of the following points?:

Coordinate Grid Practice State whether the point is on the x-axis or the y-axis. If the point is not on an axis, state which quadrant it is in.

Real WorldGo to this website and watch the video about geocaching.

Where would you create a geocaching site?Use this website to zoom in on a location you could use as a geocaching site. Create a rectangle using 4 different sites (listed by GPS coordinates) near your home. Label only 3 of the points and leave the forth incomplete so that the others can determine it from the first 3.

Still Stuck?

• Read through the “lesson” on study island.

• Come back and practice on the next slides.

Step by Step Practice

How are the locations of (1, 3) and (1, -3) related?

First plot both points. Using math terms describe their relationship.They are reflections across the x-axis.

Step by Step Practice-Check Yourself

How are the locations of (-4, 2) and (4, 2) related?

They are reflections across the y-axis.

Step by Step Practice

Plot the point.Or remember that positive x and negative y is quadrant 4.

What quadrant contains (4, -2)?

Step by Step Practice-Check Yourself

• What quadrant is (5, 3) located in?Quadrant 1

Step by Step Practice

Point is 4 places to the left so (-4,

It is also 1 place up so , 1)

(-4, 1)

Step by Step Practice-Check Yourself

(2, 1)

Step by Step Practice

• What is the distance between the points (-5, -5) and (-1, -5)?

Plot the points and count the spaces between the two points.

The distance is 4.

Step by Step Practice-Check Yourself

• What is the distance between the points (2, 4) and (2, -5)?

The distance is 9.
