Slopey Slope

Front

What is the formula to calculate the slope of a line?

Back

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

Front

Find the slope of the line that passes through the points (10, 1) and (5, 2).

Back

The slope is -1/5.

Front

Slope is known as rise over what?

Back

Slope is known as rise over run.

Front

What can be said about the slopes of parallel lines?

Back

The slopes of parallel lines are the same.

Front

What is the slope represented in the table if it shows -4?

Back

The slope is -4.

Front

Find the slope of the line that passes through the points (2, 3) and (6, 7).

Back

The slope is 1.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

If the slope of a line is 0, what does this mean?

Back

A slope of 0 means the line is horizontal.

Front

If the slope of a line is undefined, what does this mean?

Back

An undefined slope means the line is vertical.
