Rigid Transformations
Rotating to the right
Clockwise
To create a scaled copy, we multiply all the lengths in the original figure by the same number. This number is called the _________.
Scale Factor
The amount y changes when x increases by 1.
Rate of change
A part of an expression. It can be a single number, a variable, or a number and a variable multiplied together. For example, 5x+18 has two of these.
Terms
A rule that assigns exactly one output to each possible input.
Function
A graph that shows the values of two variables on a coordinate plane. Uses dots to show data points.
Scatter plot
What is the Pythagorean Theorem?
a2 + b2 = c2
Rotating to the left
Counterclockwise
A transformation that causes a shape to grow or shrink.
Dilation
Divide the vertical distance between two points by the horizontal distance to get the __________.
Slope
Multiplying the number outside of the parentheses by each term inside the parentheses.
Distributing
Represents the output of a function
Dependent variable
A data value that is far from the other data values in the data set.
Outlier
The side length of a square whose area is n. The opposite of squaring a number.
The square root
Turning
Rotating
The point that serves as the starting point from which we measure distances in a dilation.
Center of dilation
When one quantity changes by a certain amount, the other quantity always changes by a set amount in this type of relationship.
Linear relationship
Terms that have the same variable and can be combined using addition or subtraction.
Like terms
Represents the input of a function
Independent variable
When the x value increases, the y value also increases.
Positive Association
A number that cannot be written as a fraction.
Irrational Number
Flipping
Reflecting
Figures that have the same angles and proportional side lengths to the other figure are called:
Similar
Where the line crosses the y-axis
The y-intercept or the vertical intercept.
Constant
When a function is a straight line on the graph it is called a:
Linear Function
When the x value increases, the y value decreases.
Negative Association
The longest side of a triangle. This side is across from the right angle.
Hypotenuse
Sliding
Translating
Figures that are exactly the same are called:
Congruent
The equation used to show a linear relationship.
y=mx+b
What does Don't Call Me After Midnight help us to remember?
Distribute, combine like terms, move variables, add/subtract, multiply/divide.
How do you determine whether a graph is a function?
Vertical line test
When a graph is not a straight line.
Nonlinear association
The shorter two sides of a right triangle.
