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

Find the slope of the line that passes through the points (3, 5) and (7, 9).

Back

The slope is 1.

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

For every 1 unit increase in x, y increases by 2 units.

Front

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

Back

The slope is \frac{1}{3}.

Front

What is the slope of the line represented by the equation y = 3x + 2?

Back

The slope is 3.

Front

If a line has a slope of -1, what type of slope is it?

Back

It is a negative slope.
