Module 3 Flashcard

Front

What is the constant of proportionality?

Back

The constant of proportionality is the constant value (k) that relates two proportional quantities, often represented as y = kx.

Front

What does it mean for a slope to be positive?

Back

A positive slope indicates that as the x-coordinate increases, the y-coordinate also increases, resulting in an upward trend on a graph.

Front

What are the coordinates of point W?

Back

Point W has coordinates (–5, –2).

Front

What is the definition of Quadrant I in a coordinate plane?

Back

Quadrant I is the section of the coordinate plane where both x and y coordinates are positive.

Front

How do you identify the slope of a line from a graph?

Back

The slope of a line can be identified by calculating the rise over run, which is the change in y divided by the change in x.

Front

What is the significance of the number 6 in a mathematical context?

Back

The number 6 can represent a specific value in a problem, such as a solution to an equation or a quantity in a set.

Front

What are the coordinates of a point in Quadrant II?

Back

In Quadrant II, the x-coordinates are negative and the y-coordinates are positive.

Front

What does it mean for a slope to be undefined?

Back

An undefined slope occurs when a line is vertical, meaning there is no change in x, leading to division by zero.

Front

What is the formula for calculating slope?

Back

The formula for calculating slope (m) is m = (y2 - y1) / (x2 - x1).

Front

What is the definition of a coordinate plane?

Back

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