TEST: Finding Slope From Two Points & Tables

Front

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

Back

The formula for slope is: m = \frac{y2 - y1}{x2 - x1}

Front

Find the slope of the line that passes through the points (2, 4) and (6, 12).

Back

The slope is 2.

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

Find the slope of the line that passes through the points (5, -6) and (12, -6).

Back

The slope is 0.

Front

What does a slope of 0 mean?

Back

A slope of 0 means the line is horizontal.

Front

Find the slope of the line that passes through the points (9, 1) and (9, -4).

Back

The slope is undefined.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.
