Slope from Two Points & Tables

Front

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

Back

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

Calculate the slope between the points (2, 3) and (5, 11).

Back

Front

Calculate the slope between the points (1, 2) and (4, 2).

Back

The slope is 0 because the line is horizontal.

Front

Calculate the slope between the points (3, 4) and (3, 8).

Back

The slope is undefined because the line is vertical.

Front

If the slope of a line is -2, what does this tell you about the line's direction?

Back

The line falls from left to right.
