Front

Is it a function?

Back

A function is a relation where each input has exactly one output. If an input corresponds to multiple outputs, it is not a function.

Front

Find the slope of the line: (2, 3) and (4, 4)

Back

Slope = (y2 - y1) / (x2 - x1) = (4 - 3) / (4 - 2) = 1/2.

Front

What is the slope in the picture? (Line going down from left to right)

Back

Negative slope indicates that as x increases, y decreases.

Front

What is the slope in the picture? (Line going up from left to right)

Back

Positive slope indicates that as x increases, y also increases.

Front

Angles with the same measure are called ...

Back

Congruent angles.

Front

What is the definition of slope?

Back

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

Front

What does a slope of zero indicate?

Back

A slope of zero indicates a horizontal line, where y does not change as x changes.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where x does not change as y changes.

Front

What are complementary angles?

Back

Complementary angles are two angles whose measures add up to 90 degrees.

Front

What are supplementary angles?

Back

Supplementary angles are two angles whose measures add up to 180 degrees.
