Finding Slope from Two Points

Front

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

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

Given the points (1, 2) and (3, 4), what is the slope?

Back

The slope is 1.

Front

What does a positive slope indicate about a line on a graph?

Back

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

Front

Given the points (-2, -3) and (2, 3), what is the slope?

Back

The slope is 3/2.

Front

What does a negative slope indicate about a line on a graph?

Back

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

Front

Given the points (-1, 7) and (2, 2), what is the slope?

Back

The slope is -5/3.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

Given the points (-5, 5) and (-2, 7), what is the slope?

Back

The slope is 2/3.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you interpret a slope of 0?

Back

A slope of 0 means there is no change in y as x changes; the line is horizontal.
