SLOPE

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

If a line has a slope of m > 0, what does this indicate about the line's direction?

Back

The line is increasing or going upwards from left to right.

Front

What does a slope of m < 0 indicate about the line's direction?

Back

The line is decreasing or going downwards from left to right.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

What is the slope of a horizontal line?

Back

0.

Front

In the slope formula, what do 'rise' and 'run' represent?

Back

'Rise' is the change in y (vertical change), and 'run' is the change in x (horizontal change).

Front

How do you determine if a slope is positive, negative, or zero from a graph?

Back

A positive slope rises from left to right, a negative slope falls from left to right, and a zero slope is a horizontal line.

Front

What is the slope of the line that passes through the points (2, 3) and (4, 7)?

Back

2.

Front

If a line has a slope of 1, what does this mean in terms of rise and run?

Back

For every 1 unit of rise, there is 1 unit of run.

Front

What is the relationship between parallel lines in terms of slope?

Back

Parallel lines have the same slope.
