Finding Slope from a Graph Flashcard

Front

What is the formula for finding slope on a graph?

Back

Rise/Run

Front

How do you find the slope of a line given 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

If a line rises from left to right, what type of slope does it have?

Back

Positive slope.

Front

If a line falls from left to right, what type of slope does it have?

Back

Negative slope.

Front

How can you determine the slope from a graph visually?

Back

Count the vertical rise and horizontal run between two points on the line.

Front

What is the slope of the line represented by the points (2, 3) and (4, 7)?

Back

Slope = (7 - 3) / (4 - 2) = 4/2 = 2.
