GED Math Spiral Review #7 Fall 2024 Washington

Front

What is the slope of a line in the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x. It indicates how steep the line is.

Front

What does it mean for a table of values to be linear?

Back

A table is linear if the change in y is constant for equal changes in x, resulting in a straight line when graphed.

Front

How do you represent a situation where earnings are less than expenses in an inequality?

Back

You can represent it as: Earnings - Expenses < 0.

Front

What is the result of simplifying the expression (6x + 3y + 4) – (x + y – 5)?

Back

The result is 5x + 2y + 9.

Front

How do you calculate the volume of a rectangular prism?

Back

Volume = length × width × height.

Front

What is the definition of a nonlinear function?

Back

A nonlinear function is one that does not create a straight line when graphed; it may curve or have varying slopes.

Front

What does the term 'inequality' mean in mathematics?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or not equal to the other.

Front

What is the formula for the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the line crosses the y-axis, represented by the value of b in the equation y = mx + b.

Front

How do you determine if a function is increasing or decreasing?

Back

A function is increasing if the y-values rise as x-values increase, and decreasing if the y-values fall as x-values increase.
