The Number System
Any number that can be written as a simple fraction.
What is a rational number?
The letter m represents this in the equation y = mx + b.
What is the slope (or rate of change)?
A mathematical rule that assigns exactly one output to each input.
What is a function?
The formula a^2 + b^2 = c^2 is known by this name.
What is the Pythagorean Theorem?
A graph with points plotted to show a possible relationship between two sets of data.
What is a scatter plot?
The value of 3^3.
What is 27?
The letter b represents this in the equation y = mx + b.
What is the y-intercept?
The set of all possible input values (x-values) for a function.
What is the domain?
The longest side of a right triangle, represented by c.
What is the hypotenuse?
A straight line drawn through the center of the data points on a scatter plot.
What is a line of best fit (or trend line)?
Pi and the square root of 2 belong to this set of non-terminating, non-repeating numbers.
What are irrational numbers?
The solution to the equation 10 + 2x = 2x - 10.
What is no solution?
The set of all possible output values (y-values) for a function.
What is the range?
The sum of the interior angles of any triangle.
What is 180 degrees?
If both sets of data increase together, the scatter plot shows this type of association.
What is a positive association?
This is $5^-2 expressed as a fraction.
What is 1/25?
The slope of a perfectly horizontal line.
What is zero?
This visual test on a graph determines if a relation is a function.
What is the vertical line test?
A geometric transformation that slides a figure without turning it.
What is a translation?
If y-values decrease as x-values increase, the scatter plot shows this type of association.
What is a negative association?
The principal square root of 144.
What is 12?
The number of solutions for the equation 2x = x + 1.
What is one solution?
The graph of y = x^2 is classified as this type of function.
What is nonlinear?
A geometric transformation that flips a figure across a line.
What is a reflection?
A data point that lies far away from the rest of the clustered data.
What is an outlier?
