The Number System
A number that can be expressed as a ratio of two integers, b/a, where b does not =0.
What is a rational number?
The value of x that satisfies the equation 2x−3=7.
What is x=5?
A relation where each input has exactly one output.
What is a function?
A transformation that slides a figure without rotating, reflecting, or resizing it.
What is a translation?
A graph that shows the relationship between two quantitative variables.
What is a scatter plot?
The approximate value of the square root of 13 falls between these two consecutive integers.
What are 3 and 4? (Since 32=9 and 42=16)
The number of solutions for a linear equation when the variables cancel out and the remaining statement is false (e.g., 5=8).
What is no solution?
The specific type of function represented by the equation y=mx+b.
What is a linear function?
The length of the hypotenuse in a right triangle with legs of length 3 and 4.
What is 5?
A relationship between two variables where as one increases, the other also tends to increase.
What is a positive association (or positive correlation)?
The value of 3-2.
What is 1/9 ?
The solution to the system of equations: y=2x and y=x+3.
What is (3,6)?
The constant rate of change for the linear function y=4x−7.
What is 4?

What is 180 degrees?
The type of table that displays the frequencies of two categorical variables, like "Favorite Subject by Grade."
What is a two-way table (or two-way frequency table)?
When you multiply 53⋅54, the exponent in the product is this.
What is 7?
The equation resulting from 2(x+4)=18 after applying the distributive property.
What is 2x+8=18?
If you use the vertical line test on a graph, and the line intersects the graph at more than one point, this means the graph does not represent a function.
What is not a function?
The type of transformation that creates a similar figure, but not necessarily congruent.
What is a dilation?
If a segmented bar graph shows that the proportion of students who do chores and receive allowance is different from those who don't do chores and receive allowance, this indicates there is one of these between chores and allowance.
What is an association?
The set of all real numbers that are not rational.
What are irrational numbers?
The properties of exponents used to simplify (2x3)2.
What are the power of a product rule and the power of a power rule? (Result is 4x6)
The definition of the y-intercept for a linear function, which is the value of y when x is 0.
What is the initial value, or starting point?
The formula for the volume of a cylinder.
What is V=πr2h?
When analyzing a scatter plot, a data point that lies far away from the other data points.
