Calculating Slope

Front

What is the formula to calculate the slope of a line?

Back

The slope (m) is calculated using the formula: m = \frac{y_2 - y_1}{x_2 - x_1}.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-values increase, the y-values also increase, 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 the x-values increase, the y-values decrease, 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

Find the slope of the line that passes through (1, 2) and (3, 6).

Back

The slope is 2.

Front

Find the slope of the line that passes through (4, 5) and (4, 9).

Back

The slope is undefined.

Front

If a line has a slope of 3, what does this mean in terms of rise over run?

Back

For every 3 units the line rises, it runs 1 unit to the right.
