Finding Slope From a Graph

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm'. It is calculated as the change in the y-coordinate divided by the change in the x-coordinate (rise over run).

Front

How do you find the slope from a graph?

Back

To find the slope from a graph, select two points on the line, determine the rise (change in y) and run (change in x) between these points, and then divide the rise by the run.

Front

What does a positive slope indicate?

Back

A positive slope indicates that as the x-value increases, the y-value also increases, showing an upward trend.

Front

What does a negative slope indicate?

Back

A negative slope indicates that as the x-value increases, the y-value decreases, showing a downward trend.

Front

What is a zero slope?

Back

A zero slope indicates a horizontal line where there is no change in y as x changes.

Front

What is an undefined slope?

Back

An undefined slope occurs with a vertical line where the change in x is zero, leading to division by zero.

Front

If a line goes down from left to right, what type of slope does it have?

Back

It has a negative slope.

Front

If a line goes up from left to right, what type of slope does it have?

Back

It has a positive slope.

Front

What is the slope of a line that is horizontal?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a line that is vertical?

Back

The slope of a vertical line is undefined.
