Slope & Y-intercept

Front

What is the Y-INTERCEPT?

Back

The Y-intercept is the point where a line crosses the Y-axis. It is represented as the value of y when x = 0.

Front

How do you find the slope of a line?

Back

The slope of a line is calculated by taking the difference in the y-values divided by the difference in the x-values between two points on the line.

Front

What is the slope of the line represented by the equation y = 4x - 7?

Back

The slope is 4.

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

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

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.

Front

If a line has an undefined slope, what does that mean?

Back

An undefined slope means the line is vertical and does not have a defined rise over run.

Front

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

Back

The y-intercept is 5.
