What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities. It can be found by dividing one quantity by the other.

Front

Identify the constant of proportionality in the equation y = 1.50x.

Back

k = 1.50

Front

How can you tell if a graph shows a proportional relationship?

Back

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

Front

What operation is represented by the expression 6h?

Back

Multiplication.

Front

If a scale drawing shows a parking lot with a longer side measuring 6 cm, and the scale is 1 cm = 105 m, what is the actual length of the longer side?

Back

630 m.

Front

What does it mean for two quantities to be proportional?

Back

Two quantities are proportional if they maintain a constant ratio to each other.

Front

In the equation y = kx, what does 'k' represent?

Back

'k' represents the constant of proportionality.

Front

If the constant of proportionality is 3, what is the value of y when x = 4?

Back

y = 3 * 4 = 12.

Front

What is the relationship between the slope of a line and proportionality?

Back

The slope of a line in a graph represents the constant of proportionality between the two variables.

Front

How do you find the constant of proportionality from a table of values?

Back

Divide the value of y by the corresponding value of x for any pair of values.
