Finding Slope

Front

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

Back

Slope (m) = (y2 - y1) / (x2 - x1)

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

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

How do you find the slope of a line given two points (2, 4) and (6, 12)?

Back

Slope = (12 - 4) / (6 - 2) = 2.

Front

If a line has a slope of 4/3, what does this mean in terms of rise over run?

Back

For every 4 units the line rises, it runs 3 units to the right.

Front

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

Back

The slope is 3.

Front

If the slope of a line is 1/3, what is the angle of inclination of the line?

Back

The angle of inclination is approximately 18.43 degrees.

Front

What is the slope of the line that passes through the points (1, 2) and (3, 6)?

Back

Slope = (6 - 2) / (3 - 1) = 2.
