Front

What is the rate of change?

Back

The rate of change is the ratio of the change in the dependent variable to the change in the independent variable, often represented as slope in a graph.

Front

How do you find the slope of a line from an equation?

Back

To find the slope from an equation in the form y = mx + b, identify the coefficient of x (m) as the slope.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the value of y when x = 0, represented by b in the equation y = mx + b.

Front

What does a slope of 7/4 indicate?

Back

A slope of 7/4 indicates that for every 4 units you move horizontally, the line rises 7 units vertically.

Front

How do you calculate average rate of change?

Back

Average rate of change = (Change in altitude) / (Change in time).

Front

What is a reflection in geometry?

Back

A reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What does a 90° clockwise rotation mean?

Back

A 90° clockwise rotation means turning a figure 90 degrees to the right around a point.

Front

What is the formula for calculating slope?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What does it mean if the rate of change is negative?

Back

A negative rate of change indicates that as the independent variable increases, the dependent variable decreases.

Front

How do you interpret a slope of 2 burgers per person?

Back

A slope of 2 burgers per person means that for every person, 2 burgers are served.
