HOW TO GRAPH POINTS ON A GRIDGraphing points on a grid can be hard, but once youknow how to do it, it can be really easy! When Istarted out, I had no idea how to graph points on agrid, but now I have no trouble. If you are havingproblems learning to graph, I will teach you how.
LESSON GOALS• Learn how to use the X and Y axis to graph points on a grid• Learn how to start from the origin and go on from there
GROUND WORKFirst, we need to learn how to use the X and Y axis.Here is an example of what the X and Y axis look like: Y Usually, you will see the axis on a grid Here is what that looks like: X
THE ORIGINThe origin is an essential part of learning how to plotpoints on a graph. The origin is 0, or, on a graph:You will always start from the origin,and move on from there.Where you go will be determined by the coordinates.
WHAT DO I DO WITH ALL THESE COORDINATES?Coordinates are a pair of two numbers that tell youwhere to graph a point on a grid. Here is an exampleof what coordinates look like:5,3-9,46,-8One thing that you need to know is that if one of thenumbers is a negative, that means that the point willbe on the left hand side (vertically) and at the bottom(horizontally) on the grid.
HOW TO GRAPH POINTS ON A GRIDFinally, we have come to the point where I show youwhere to graph a point on a Grid. One very importantthing that you need to know is that the first number ina coordinate is a number on the X, or horizontal, axis.The second number represents Y, which is plotted onthe vertical axis. The next 4 slides are examples.
1The This is whereCoordinates theseare 3,5 coordinates require us to plot the point on our graph.
The Coordinat 2 es are -9,-7This iswhere -9,-7 isLocated.
The 3 Coordinat es are -4,7This iswhere -4,7 islocated.
The 4Coordinates are 6,-10 This is where 6,- 10 is located on the grid.
EXAMPLE PROBLEMSNow it is time for me to leave you and for you topractice some problems on your own. Remember thatyou always start at the origin (0,0 on the graph.)Then, remember that move first along the X axis, andthen plot along the Y axis. Finally, remember thatpositive numbers will be found in the upper rightsection of the grid, while negative numbers will befound in the lower left section of the grid.
REVIEWSo, in review, we learned how to graph points on agrid. We learned that you need to start on the origin,and move on from there. We learned that thenegative numbers are found in the lower left side ofthe grid, and the positive are found in the upper rightside. I hope you learned a lot from this presentation!
