Additive and Multiplicative Review

Front

What is the difference between additive and multiplicative relationships?

Back

Additive relationships involve adding a constant value, while multiplicative relationships involve multiplying by a constant factor.

Define a linear equation.

Back

A linear equation is an equation that makes a straight line when graphed, typically in the form y = mx + b.

Front

What does the slope of a line represent in a graph?

Back

The slope represents the rate of change of y with respect to x, indicating how steep the line is.

Front

What is the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

How do you find the cost of multiple items if each item has a fixed price?

Back

Multiply the price of one item by the number of items: Total Cost = Price per Item × Number of Items.

What is the equation to find the total cost (c) of b bookmarks if each bookmark costs $0.79?

Back

c = 0.79b.

If Victoria receives $7.50 each week, how can we express the total amount she saves after x weeks?

Back

Total Savings = 7.50x.

Front

What is the equation to determine how many weeks (x) Victoria needs to save to buy a bicycle costing $90?

Back

$7.50x = 90.

Front

What does it mean if a table of values shows a constant rate of change?

Back

It indicates a linear relationship between the variables.

Front

How can you identify a multiplicative relationship from a table of values?

Back

If the ratio of the values remains constant, it indicates a multiplicative relationship.
