What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where the ratio of one quantity to the other quantity is constant.

Front

What is the equation of a proportional relationship?

Back

The equation of a proportional relationship can be written in the form y = kx, where k is the constant of proportionality.

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities.

Front

How do you determine if an equation is proportional?

Back

An equation is proportional if it can be rewritten in the form y = kx, meaning it does not have a constant added or subtracted.

Front

What is the probability of an event?

Back

The probability of an event is a measure of the likelihood that the event will occur, calculated as the number of favorable outcomes divided by the total number of possible outcomes.

Front

How do you calculate the area of a circle?

Back

The area of a circle is calculated using the formula A = πr², where r is the radius of the circle.

Front

What is a composite figure?

Back

A composite figure is a shape that is made up of two or more simple geometric shapes.

Front

How do you find the area of a composite figure?

Back

To find the area of a composite figure, calculate the area of each simple shape and then sum those areas.

Front

What is a graph of a proportional relationship?

Back

A graph of a proportional relationship is a straight line that passes through the origin (0,0).

Front

What does it mean for a graph to be proportional?

Back

A graph is proportional if it shows a constant ratio between the x and y values, resulting in a straight line through the origin.
