Slope from a Graph

Front

What is slope?

Back

Slope is the ratio of rise over run, vertical change over horizontal change, or change in y over change in x.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What does a slope of 0 indicate?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate?

Back

An undefined slope indicates that the line is vertical.

Front

How do you calculate the slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the slope of the line represented by the equation y = 4x + 2?

Back

The slope of the line is 4.

Front

What is the slope of the line represented by the equation y = -1/2x + 3?

Back

The slope of the line is -1/2.

Front

If a line goes up from left to right, what can you say about its slope?

Back

The slope is positive.

Front

If a line goes down from left to right, what can you say about its slope?

Back

The slope is negative.

Front

What is the slope of the line represented by the equation y = 0?

Back

The slope is 0.
