Front

What is the constant of proportionality?

Back

The constant of proportionality is the ratio between two proportional quantities, often represented as the unit rate or unit price.

Front

What does the initial value of a graph represent?

Back

The initial value of a graph is the y-coordinate where the graph intersects the y-axis, indicating the starting point of the function.

Front

Identify the Y-INTERCEPT from the equation: y=5/2x + 3.

Back

The Y-INTERCEPT is 3.

Front

What is the slope of the line represented by the equation y=3x + 2?

Back

The slope of the line is 3.

Front

What is a function?

Back

A function is a relation where each input has exactly one output.

Front

What is a unit rate?

Back

A unit rate is a ratio that compares a quantity to one unit of another quantity.

Front

How do you find the slope of a line from its equation?

Back

The slope can be found from the equation in the form y = mx + b, where m is the slope.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as the x-value increases, the y-value also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as the x-value increases, the y-value decreases.

Front

What is the difference between a function and a non-function?

Back

A function has one output for each input, while a non-function may have multiple outputs for a single input.
