Slope Flashcard

Front

What is the formula that we use to calculate slope?

Back

The formula for slope (m) is: m = (y2 - y1) / (x2 - x1)

Front

Find the slope of the line that passes through the points (2, 3) and (5, 7).

Back

The slope is 4/3.

Front

Find the slope of the line that passes through the points (1, 2) and (4, 0).

Back

The slope is -2/3.

Front

Find the slope of the line that passes through the points (-10, 1) and (5, -2).

Back

The slope is -1/5.

Front

Find the slope of the line that passes through the points (-2, 8) and (0, 8).

Back

The slope is 0.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

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 vertical line?

Back

The slope of a vertical line is undefined.

Front

How do you find the slope from a graph?

Back

To find the slope from a graph, choose two points on the line, and use the formula: m = (change in y) / (change in x).
