8MA Unit 2B Review

Front

What is the equation to model the total cost, y, for ordering x candles if the flat rate shipping is $7.50 and the cost of 4 candles is $35?

Back

Front

What does the y-intercept represent in a linear function?

Back

The y-intercept is the value of y when x = 0, representing the starting point of the function.

Front

If Function A has a y-intercept that is 1 unit greater than Function B, what can we say about their graphs?

Back

Function A's graph starts higher on the y-axis compared to Function B's graph.

Front

How do you determine the slope of a linear equation?

Back

The slope is the coefficient of x in the equation, representing the rate of change of y with respect to x.

Front

What does the slope of the equation y = 20x + 85 represent in the context of saving money?

Back

The slope (20) represents the amount of money Alan earns each week mowing the lawn.

Front

What does the y-intercept of the equation y = 20x + 85 represent?

Back

The y-intercept (85) represents the initial amount of money Alan already has saved.

Front

Create an equation for a line with a slope of 5 and a y-intercept of 100.

Back

Front

What is the significance of the flat rate shipping cost in the total cost equation?

Back

It is a fixed cost added to the total cost of the items ordered.

Front

If Zachary is saving the least amount of money per day, what can we infer about his savings compared to Maya and Abigail?

Back

Zachary's daily savings amount is less than both Maya's and Abigail's.

Front

How do you compare the y-intercepts of two functions?

Back

By evaluating the y-values of both functions when x = 0.
