Identifying Slope and Y-Intercept

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise (change in y) over the run (change in x).

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

How do you identify the y-intercept in an equation?

Back

The y-intercept is the value of y when x is 0, often represented as the constant term in the equation of a line.

Front

In the equation y = mx + b, what does 'm' represent?

Back

'm' represents the slope of the line.

Front

In the equation y = mx + b, what does 'b' represent?

Back

'b' represents the y-intercept of the line.

Front

What is the y-intercept of the equation y = -3x + 1?

Back

The y-intercept is 1.

Front

What is the y-intercept of the equation y = 2x + 5?

Back

The y-intercept is 5.

Front

What is the slope of the equation y = 2x - 1?

Back

The slope is 2.

Front

If a line has a slope of 0, what does that mean?

Back

A slope of 0 means the line is horizontal and does not rise or fall.
