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

How do you find the slope of a line given two points?

Back

To find the slope, subtract the y-coordinates and divide by the difference of the x-coordinates: m = (y2 - y1) / (x2 - x1).

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

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

If the slope of a line is 2, what does this mean?

Back

This means that for every 1 unit increase in x, y increases by 2 units.

Front

What does 'm' represent in the slope formula?

Back

In the slope formula, 'm' represents the slope of the line.

Front

Find the slope of the line that passes through (3, 4) and (7, 8).

Back

The slope is m = (8 - 4) / (7 - 3) = 4 / 4 = 1.

Front

Find the slope of the line that passes through (1, 2) and (4, 5).

Back

The slope is m = (5 - 2) / (4 - 1) = 3 / 3 = 1.
