Slope formula

Front

What is the slope formula?

Back

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

Front

What does 'm' represent in the slope formula?

Back

'm' represents the slope of the line.

Front

What is a positive slope?

Back

A positive slope indicates that as x increases, y also increases, resulting in an upward slant from left to right.

Front

What is a negative slope?

Back

A negative slope indicates that as x increases, y decreases, resulting in a downward slant from left to right.

Front

What is a zero slope?

Back

A zero slope indicates a horizontal line where y remains constant as x changes.

Front

What is an undefined slope?

Back

An undefined slope occurs with a vertical line where x remains constant and y changes.

Front

How do you find the slope between two points (3, 4) and (7, 8)?

Back

Using the slope formula: m = (8 - 4) / (7 - 3) = 4 / 4 = 1.

Front

If a line has a slope of -5/4, what type of slope is it?

Back

It is a negative slope.

Front

If a line is horizontal, what is its slope?

Back

The slope is zero.

Front

If a line is vertical, what is its slope?

Back

The slope is undefined.
