Front

What is the RATE OF CHANGE?

Back

The rate of change in a linear function represents how much the output (y) changes for a change in the input (x). It is often referred to as the slope.

Front

Back

The slope (m) indicates the steepness of the line and the direction it goes. A positive slope means the line rises, while a negative slope means it falls.

Front

What is another word for an x-intercept?

Back

Zero.

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

Back

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal and there is no change in y as x changes.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical, meaning x does not change as y changes.

Front

Back

The y-intercept (b) is the point where the line crosses the y-axis.

Front

If a line has a slope of -2, what does this tell you about the line's direction?

Back

The line falls as it moves from left to right.
