Front

What is a proportional relationship?

Back

A proportional relationship is a relationship between two quantities where their ratio is constant. This means that as one quantity increases, the other quantity increases at a consistent rate.

Front

What does it mean if a graph does not go through the origin?

Back

If a graph does not go through the origin, it indicates that the relationship is non-proportional. This means that the ratio of the two quantities is not constant.

Front

How can you identify a proportional graph?

Back

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

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).

Front

What is the formula for the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

Front

What does it mean for two quantities to be non-proportional?

Back

Two quantities are non-proportional if their ratio changes as the quantities change, meaning they do not maintain a constant relationship.

Front

What is an algebra tile?

Back

An algebra tile is a manipulative used to represent algebraic expressions and equations visually. They can represent variables and constants.

Front

How do you combine like terms in algebra?

Back

To combine like terms, add or subtract the coefficients of terms that have the same variable raised to the same power.

Front

What is the significance of the origin in a graph?

Back

The origin (0,0) is significant in a graph as it represents the point where both the x-axis and y-axis intersect, indicating the starting point of the relationship.

Front

What is a straight line graph?

Back

A straight line graph represents a linear relationship between two variables, where the change in one variable is consistent with the change in the other.
