Front

What is the definition of slope?

Back

The slope is a measure of the steepness or incline of a line, calculated as the ratio of the vertical change to the horizontal change between two points on the line.

How do you calculate the slope from a table of values?

Back

To calculate the slope from a table, use the formula: slope (m) = (change in y) / (change in x) between two points.

If the coordinates of two points are (2, 3) and (4, 7), what is the slope?

Back

The slope is (7 - 3) / (4 - 2) = 4 / 2 = 2.

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, as there is no vertical change.

If the slope is 1/4, what does this mean in terms of rise over run?

Back

It means for every 1 unit of vertical rise, there is a 4 unit horizontal run.

What is the slope of the line represented by the points (1, 2) and (3, 6)?

Back

The slope is (6 - 2) / (3 - 1) = 4 / 2 = 2.

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

Back

It indicates that the line descends from left to right.
