Finding Slope

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 y (vertical change) divided by the change in x (horizontal change).

Front

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

Back

Front

What is the slope of the line through the points (20, 8) and (9, 16)?

Back

Front

What is the y-intercept in the equation y = 5x - 3?

Back

The y-intercept is the value of y when x = 0. In this equation, the y-intercept is -3.

Front

What is the slope-intercept form of a linear equation?

Back

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases, 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 x increases, y decreases, meaning the line falls from left to right.

Front

What is the slope of the line represented by the equation y = -2x + 4?

Back

The slope of the line is -2.

Front

If the slope of a line is 0, what does this mean?

Back

A slope of 0 means the line is horizontal, indicating that there is no change in y as x changes.

Front

If the slope of a line is undefined, what does this mean?

Back

An undefined slope means the line is vertical, indicating that there is no change in x as y changes.
