5.7 Graph on the Coordinate Plane Lesson

5.7 Graphing on the Coordinate Plane

​Graphing on the Coordinate Plane Song

​The last lesson we identified ordered pairs today we will graph them on our whiteboards. Let's first review identifying ordered pairs.

Multiple Choice

What is the ordered pair for P?

• (-2,4)

• (4,-2)

• $$\left(-\frac{1}{2},\ -2\frac{1}{2}\right)$$  

• (4.5,1)

Multiple Choice

What is the ordered pair for Q?

• (4,0)

• (0,-4)

• $$\left(-\frac{1}{2},\ -2\frac{1}{2}\right)$$  

• (4.5,1)

​Start at the origin (0,0)

• ​If x is positve move to the right, if negative move to the left, if 0 do not move stay at (0,0). Remember Shuffle on the Carpet, if it is zero you do not shuffle anywhere.

• ​From that spot, if y is positive move up, if y is negative move down, if 0 do not move. Climb up or down the stairs.

• ​Put your point at that spot.

​Your Turn. Graph the following points on your whiteboard.

A: ​(1,1)

B:​ (-2,2)

C: (-4,-2)​

D: (5,-4)​​

​

​

• ​Points reflected across the x-axis will have the same x-coordinate and their y-coordinates will be opposites.(x,y) and (x,-y)

• ​Points reflected across the y-axis will have the same y-coordinates and their x-coordinates will be opposites.(x,y) and (-x,y)

​Remember

Multiple Choice

(-1,5)

What is the point reflected across the x-axis? 

• (-1,5)

• (1,5)

• (-1,-5)

• (1,-5)

Multiple Choice

(2,5)

What is the point reflected across the y-axis? 

• (2,5)

• (-2,5)

• (-2,-5)

• (2,-5)

​Graph the Point and its Reflection on your Whiteboard

​

A: (1,3)​​ and Point A^ that is reflected across the x-axis.

​

​B: (-8,7)​​ and Point B^ that is reflected across the y-axis.
