Slope on a graph

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the change in the vertical direction (rise) divided by the change in the horizontal direction (run).

Front

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

Back

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

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as you move from left to right on the graph, the line rises.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as you move from left to right on the graph, the line falls.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is zero.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

If a line has a slope of 4/3, what does this mean?

Back

For every 4 units the line rises, it moves 3 units to the right.

Front

What is the slope of the line represented by the equation y = -2x + 5?

Back

The slope is -2.

Front

How can you identify the slope from a graph?

Back

You can identify the slope by selecting two points on the line and calculating the rise over run.

Front

What does it mean if a line has a slope of 1?

Back

It means that for every 1 unit the line rises, it also moves 1 unit to the right.
