What is the formula for the area of a rectangle?

Back

Area = length × width.

Front

If the length of a rectangular garden is 2 feet greater than its width, how can we express the length in terms of width?

Back

Length = w + 2, where w is the width.

Front

What does the equation N = w² + 6w + 8 represent in the context of a garden's area?

Back

It represents the new area of the garden after increasing both dimensions by 2 feet.

Front

How do you find a coordinate point on the graph of a function?

Back

Substitute the x-value into the function to find the corresponding y-value.

Front

What is the value of f(-2) if f(x) = -1.5x - 1?

Back

f(-2) = 2, so the coordinate point is (-2, 2).

Front

What is a linear function?

Back

A function that graphs to a straight line, typically in the form f(x) = mx + b.

Front

How can you represent a sequence mathematically?

Back

By writing a function that describes the pattern of the sequence.

Front

What does the slope of a linear equation represent?

Back

The rate of change of the dependent variable with respect to the independent variable.

Front

In the equation y = 461.19x + 3,492, what does 461.19 represent?

Back

The yearly increase in value of the work of art.

Front

What does it mean for two lines to be parallel?

Back
