What is the slope of a line?

Back

The slope of a line is a measure of its steepness, typically represented as 'm' in the equation of a line. It is calculated as the change in y divided by the change in x (rise/run).

Front

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

Back

The slope (m) can be found using the formula: m = (y2 - y1) / (x2 - x1).

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-values increase, the y-values decrease, meaning the line falls from left to right.

Front

What is a vertical translation in graph transformations?

Back

A vertical translation shifts the graph up or down without changing its shape.

Front

What is a horizontal translation in graph transformations?

Back

A horizontal translation shifts the graph left or right without changing its shape.

Front

In the vertex form f(x) = a(x - h)² + k, what does 'k' represent?

Back

'k' represents the vertical shift of the graph; it moves the graph up if k is positive and down if k is negative.

Front

What is the parent function of an exponential function?

Back

The parent function of an exponential function is f(x) = a^x, where 'a' is a positive constant.

Front

How does the 'h' value in the vertex form affect the graph?

Back

'h' shifts the graph left or right; if h is positive, the graph shifts to the right, and if h is negative, it shifts to the left.

Front

What does a scatter plot show?

Back

A scatter plot shows the relationship between two variables, indicating how one variable may change in relation to another.

Front

What does a non-linear association in a scatter plot indicate?

Back

A non-linear association indicates that the relationship between the variables does not follow a straight line; it may curve or change direction.
