Finding Slope

Front

What is the formula for finding the slope of a line?

Back

Slope (m) = (change in y) / (change in x)

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

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

Back

Slope = 2

Front

If the slope of a line is negative, what does that indicate about the line's direction?

Back

The line descends from left to right.

Front

What does a slope of 0 mean in terms of a line?

Back

The line is horizontal.

Front

What does an undefined slope indicate?

Back

The line is vertical.

Front

Find the slope of the line that passes through the points (2, 3) and (5, 11).

Back

Slope = (11 - 3) / (5 - 2) = 8/3

Front

Calculate the slope of the line that passes through the points (-1, 4) and (2, 7).

Back

Slope = (7 - 4) / (2 - (-1)) = 3/3 = 1

Front

What is the slope of the line that passes through the points (0, 0) and (4, 8)?

Back

Slope = (8 - 0) / (4 - 0) = 2

Front

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

Back

For every 3 units of rise, there is a 1 unit run.
