Slope 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

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

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-values increase, the y-values also increase, meaning the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, meaning 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, indicating that there is no vertical change as the x-values change.

Front

What does an undefined slope mean?

Back

An undefined slope occurs in a vertical line where the x-values are constant, indicating that there is no horizontal change.

Front

If a line rises 3 units for every 4 units it runs, what is the slope?

Back

Slope = 3/4

Front

If a line falls 2 units for every 5 units it runs, what is the slope?

Back

Slope = -2/5

Front

What is the slope of a line that goes through the points (1, 2) and (3, 6)?

Back

Slope = (6 - 2) / (3 - 1) = 4/2 = 2

Front

What is the slope of a line that goes through the points (2, 3) and (2, 5)?

Back

Slope = (5 - 3) / (2 - 2) = Undefined (vertical line)
