Graphing
The first number in the coordinate pair is called this.
What is the x coordinate?
When reflecting a point over the x-axis, which coordinate stays the same?
What is the first coordinate, or x coordinate.
This is the operation you use to find the perimeter of a rectangle.
What is addition.
This is the direction you move first when graphing a point.
What is right or left of the origin?
When reflecting point "P" over an axis, it becomes this point.
What is "P'", or "P prime".
A=bh (base times height) or A=lw (length times width) are formulas for finding this.
What is area, or the area of a rectangle.
The second number in the coordinate pairs is this.
What is the y- coordinate?
When reflecting (4,5) over the x-axis, it will land in this quadrant.
What is quadrant 4, or IV.
This is the distance between (0,0) and (0,6).
What is 6, or 6 units.
This is the direction you move second when graphing a point.
What is vertically or up and down?
When reflecting a point over the y-axis, this coordinate becomes its OPPOSITE.
What is the x coordinate, or the first coordinate.
These are the kinds of units used to measure area.
What are square units, or units squared.
The ORIGIN on the coordinate plane is located where the x-axis and y-axis cross. This is the coordinate of that point.
What is (0, 0)?
This is where you start graphing.
What is the origin (0,0)?
This is where the image of (5,-2) will be after it is reflected over the y-axis.
What is ( -5,-2)
This is why you can't find the perimeter of a triangle on a grid without a special formula.
You can not find the length of a slant or diagonal line.
or
You can only find the length of horizontal and vertical lines.
