Slope Triangles Modified

Front

What is the definition of slope in a triangle?

Back

The slope of a triangle is the ratio of the vertical change (rise) to the horizontal change (run) between two points on a line.

Front

How do you calculate the slope using slope triangles?

Back

To calculate the slope using slope triangles, divide the length of the vertical side (rise) by the length of the horizontal side (run).

Front

What does a slope of 2 indicate about a line?

Back

A slope of 2 indicates that for every 1 unit the line moves horizontally, it moves 2 units vertically.

Front

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

Back

The slope of a perfectly horizontal line is 0.

Front

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

Back

The slope of a perfectly vertical line is undefined.

Front

If two triangles are similar, what can be said about their slopes?

Back

If two triangles are similar, their slopes are equal.

Front

What is the slope of triangle ABC if it is given as 1?

Back

The slope of triangle ABC is 1, meaning it rises 1 unit for every 1 unit it runs.

Front

How can you determine the slope from a graph?

Back

To determine the slope from a graph, select two points on the line, find the rise and run between them, and calculate the slope as rise/run.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line descends from left to right.

Front

What is the formula for slope?

Back

The formula for slope (m) is m = (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on the line.
