Homework for Friday 10-4: page 86, items 10, 11, 12, 13, 14
Today in class we investigated the changes in x (left and right movement) and the changes in y (up and down movement) as we trace along the graph of a straight line. We did the exercises on pages 84 and 85.
Slope is vertical change divided by horizontal change.
Slope is change in y divided by change in x.
Slope is rise divided by run.
Slope is "up" divided by "over.
Slope is a ratio that can be an integer, a fraction or a decimal.
The slope of a straight line is the same everywhere along the line.
Slope is a measure of the steepness, the uphillness or downhillness, of a line.
Since a slope is a ratio, its units are the numerator units divided by the denominator units.
Slope is the ratio of output to a given input.
