W21 VOCABULARY Unit 08 Coordinate Plane Concepts Flashcard

Front

What is an additive relationship in mathematics?

Back

An additive relationship is when a constant non-zero value is added to an input value to determine the output value.

Front

Which of the following is a rational number? (Options: √2, 3/4, π, e)

Back

3/4 is a rational number.

Front

What are the axes in a coordinate plane?

Back

The axes are the vertical and horizontal lines that act as a reference when plotting points.

Front

In the equation y = 3x + 5, what is the coefficient?

Back

The coefficient is 3.

Front

In a function, what is the dependent variable?

Back

The dependent variable is the variable that represents the output value.

Front

What is a coordinate plane?

Back

A coordinate plane is a two-dimensional surface formed by the intersection of a vertical line (y-axis) and a horizontal line (x-axis).

Front

What does the x-axis represent in a coordinate plane?

Back

The x-axis represents the horizontal line in a coordinate plane.

Front

What does the y-axis represent in a coordinate plane?

Back

The y-axis represents the vertical line in a coordinate plane.

Front

What is the origin in a coordinate plane?

Back

The origin is the point where the x-axis and y-axis intersect, represented as (0, 0).

Front

What is the slope in a linear equation?

Back

The slope is the ratio of the rise (change in y) to the run (change in x) between two points on a line.
