Slope Practice (From a Graph)

Front

What is the definition of slope in a graph?

Back

Slope is a measure of the steepness or incline of a line, calculated as the ratio of the vertical change (rise) to the horizontal change (run) between two points on the line.

Front

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

Back

The slope (m) is calculated using the formula: m = (y2 - y1) / (x2 - x1).

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.

Front

In which quadrant would you find the ordered pair (3, -2)?

Back

The ordered pair (3, -2) is located in Quadrant IV.

Front

What is the slope of a line that rises 4 units and runs 2 units?

Back

The slope is 4/2, which simplifies to 2.

Front

What does a positive slope indicate about a line?

Back

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

Front

What does a negative slope indicate about a line?

Back

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

Front

How can you determine if a slope is undefined from a graph?

Back

A slope is undefined if the line is vertical, meaning it does not have a defined rise over run.

Front

What is the ordered pair for the x-intercept of a line?

Back

The ordered pair for the x-intercept is (x, 0), where y equals 0.
