Slope & Slope Intercept Form Review

Front

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

Front

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

Front

What does a positive slope indicate about a line on a graph?

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 on a graph?

Back

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

Back

The y-intercept is 4, which is the point where the line crosses the y-axis.

Front

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

Back

An undefined slope means the line is vertical, and it does not have a defined slope value.

Front

What does the slope represent in a real-world context, such as salary per movie?

Back

The slope represents the rate of change, such as how much salary increases for each additional movie.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0, indicating no change in y as x changes.
