Constant of Proportionality Graphs Tables Equations

Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as 'k' in the equation y = kx.

Front

What is the formula for a proportional relationship?

Back

y = kx

Front

How do you find the constant of proportionality from a graph?

Back

You find the constant of proportionality by determining the unit rate, which is the value of y when x is 1.

Front

What does a unit rate represent?

Back

A unit rate represents a quantity of one unit of another quantity, showing how much of one item corresponds to one unit of another.

Front

If y = 18.50x, what is the constant of proportionality?

Back

The constant of proportionality is 18.50.

Front

Which graph represents a proportional relationship?

Back

A graph that passes through the origin (0,0) and has a straight line.

Front

What is the unit rate for 2 boys for every 1 girl?

Back

The unit rate is 2 boys per girl.

Front

How can you express a proportional relationship in an equation?

Back

By using the formula y = kx, where k is the constant of proportionality.

Front

What does it mean if a graph is not linear?

Back

If a graph is not linear, it does not represent a proportional relationship, as proportional relationships must be straight lines through the origin.

Front

What is the relationship between tables and graphs in proportional relationships?

Back

Tables can be used to find points that can be plotted on a graph, and the graph visually represents the proportional relationship.
