Front

What is the result of a rotation of 180° in any direction on line segments?

Back

The line segments from the pre-image and image have the same slope.

Front

What is the equation of the line represented by the graph where y is constant?

Back

y = 3

Front

Back

x = -2y + 77

Front

What determines if a mapping diagram represents a function?

Back

A mapping diagram represents a function if there are no repeating input values.

Front

How do you calculate the rate of change from a given distance over time?

Back

Rate = Distance / Time. For Mrs. Gordon, the rate from 0 to 2 seconds is 2.5 feet per second.

Front

What is the definition of a function in mathematics?

Back

A function is a relation that assigns exactly one output for each input.

Front

What is the slope of a line?

Back

The slope is a measure of the steepness of a line, calculated as the rise over run.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the standard form of a linear equation?

Back

The standard form is Ax + By = C, where A, B, and C are integers.

Front

What does it mean for two lines to be parallel?

Back

Two lines are parallel if they have the same slope and never intersect.
