Intro to Slope

Front

What is the definition of slope?

Back

Slope is a measure of the steepness of a line, calculated as the ratio of vertical change (rise) to horizontal change (run).

Front

How is slope represented mathematically?

Back

Slope is written as the fraction Height over Base (rise/run).

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal and there is no vertical change.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates that the line is vertical, meaning there is no horizontal change.

Front

What is the formula to calculate slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

If a line rises from left to right, what can be said about its slope?

Back

If a line rises from left to right, its slope is positive.

Front

If a line falls from left to right, what can be said about its slope?

Back

If a line falls from left to right, its slope is negative.

Front

What is the relationship between the slopes of two congruent triangles on a graph?

Back

The slopes of two congruent triangles are the same.

Front

True or False: The base of a triangle represents the vertical change.

Back

False. The base represents the horizontal change.

Front

What is the slope of a line that is perfectly vertical?

Back

The slope of a perfectly vertical line is undefined.
