Slope Review

Front

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

Back

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

Front

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

Back

Slope = (6 - 2) / (3 - 1) = 4 / 2 = 2

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

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

Back

Slope = (7 - 3) / (5 - 2) = 4 / 3

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

When we talk about slope, we are talking about how _____ a line is on a graph.

Back

steep

Front

Find the slope of the line that passes through the points (4, 5) and (6, 9).

Back

Slope = (9 - 5) / (6 - 4) = 4 / 2 = 2

Front

If a line has a slope of -3, what does this tell us about the line's direction?

Back

The line falls steeply as it moves from left to right.
