A3B-Slope from two points

Front

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

Back

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

Front

Find the slope of the line that passes through the points (1, 2) and (3, 4).

Back

1

Front

What does a slope of 0 indicate about a line?

Back

The line is horizontal.

Front

What does a positive slope indicate about the direction of a line?

Back

The line rises from left to right.

Front

What does a negative slope indicate about the direction of a line?

Back

The line falls from left to right.

Front

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

Back

Undefined (vertical line).

Front

If the slope of a line is 2, what does this mean in terms of rise over run?

Back

For every 2 units up (rise), the line goes 1 unit to the right (run).

Front

Find the slope of the line that passes through the points (4, 1) and (6, 1).

Back

0 (horizontal line).

Front

What is the slope of a vertical line?

Back

Undefined.
