Finding Slope From Two Points

Front

What is the slope?

Back

The slope is a measure of the steepness of a line, calculated as the change in y divided by the change in x (rise/run).

Front

Find the slope given these points: (-8,4) & (-5,1)

Back

The slope is -1.

Front

What is the slope?

Back

The slope is 5/2.

Front

Find the slope given these points: (-2,-3) & (2,3)

Back

The slope is 3/2.

Front

Find the slope of the line through each pair of points: (1,2) & (3,4)

Back

The slope is 1.

Front

What is the formula for calculating slope?

Back

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

Front

If the slope is positive, what does that indicate about the line?

Back

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

Front

If the slope is negative, what does that indicate about the line?

Back

A negative slope indicates that the line falls from left to right.

Front

What does a slope of zero mean?

Back

A slope of zero means the line is horizontal.

Front

What does an undefined slope mean?

Back

An undefined slope means the line is vertical.
