Finding Slope Flashcard

Front

What is the formula to find the slope of a line?

Back

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

Front

What does the slope of a line represent?

Back

The slope represents the rate of change of y with respect to x.

Front

Find the slope of the line that passes through (10, 1) and (5, 2).

Front

Find the slope from the table: (x1, y1) = (0, 0), (x2, y2) = (5, -2).

Front

What is 'rise' in the context of slope?

Back

Rise is the change in the y-coordinates (y2 - y1).

Front

What is 'run' in the context of slope?

Back

Run is the change in the x-coordinates (x2 - x1).

Front

Which of the following are ways to find the rate of change?

Back

All of the above: change in y over change in x, rise over run, subtract y coordinates over subtract x coordinates.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises as it moves from left to right.
