Basic Coordinates
The horizontal axis on a coordinate plane.
What is the x-axis?
An angle less than 90 degrees
What is an acute angle?
A transformation that slides a figure in any directions.
What is a translation?
The point where the line crosses the y-axis.
What is the y-intercept?
If you reflect the point (3,4) over the y-axis, the new coordinates are this.
What are (-3,4)?
Coordinates for the origin of the coordinate plane.
What is (0,0)?
An angle measuring exactly 90 degrees.
A transformation that flips a figure over a line.
What is a relflection?
The slope of a horizontal line.
What is 0?
If you reflect the point (5,6) over the x-axis, the new coordinates are this.
What are (5,-6)?
The vertical axis on a coordinate plane.
What is the y-axis?
An angle greater than 180 degrees but less than 360 degrees.
What is a reflex angle?
A transformation that turns a figure around a point.
What is a rotation?
The intersection of the x-axis and the y-axis is called this.
What is the origin?
What are a ruler and graph paper?
An ordered pair indicating a point on the coordinate plane.
What is (x,y)?
Two angles that add up to 180 degrees.
What are supplementary angles?
The transformation that enlarges or reduces a figure by a scale factor.
What is a dilation?
The change in y-values divided by the change in x-values in a linear equation.
What is slope?
The new coordinates of (2,-3) after a 180 degree rotation around the origin.
What is (-2,3)?
The quadrant where both the x and y are positive.
What is Quadrant 1?
Two angles that add up to 90 degrees.
What are complimentary angles?
If a figure is translated 3 units to the right and 1 unit up, what is the coordinate change?
What is (x+3, y+1)?
The slope-intercept form of a linear equation.
What is y=mx + b?
The coordinates after translating (1,-2) by (4,5).
What are (5,3)?
