What is an inequality in mathematics?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, greater than or equal to, or less than or equal to the other.

How do you reflect a point over the x-axis?

Back

To reflect a point (x, y) over the x-axis, you change the sign of the y-coordinate, resulting in the point (x, -y).

Front

What is a y-intercept?

Back

The y-intercept is the point where a line crosses the y-axis, represented as (0, y). It indicates the value of y when x is 0.

Front

What does it mean for two angles to be equal?

Back

Two angles are equal if they have the same measure in degrees or radians.

Front

What is a linear model?

Back

A linear model is a mathematical representation of a relationship between two variables that can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is a vertical translation in geometry?

Back

A vertical translation moves a shape up or down in the coordinate plane without changing its shape or orientation.

Front

How do you determine the slope of a line from a linear equation?

Back

The slope of a line in the equation y = mx + b is represented by m, indicating the rate of change of y with respect to x.

Front

What is the significance of the slope in a linear model?

Back

The slope indicates how much the dependent variable (y) changes for each unit increase in the independent variable (x).

Front

What is the formula for finding the area of a rectangle?

Back

The area of a rectangle is calculated using the formula Area = length × width.

Front

What is a transformation in geometry?

Back

A transformation is an operation that moves or changes a shape in some way, including translations, rotations, reflections, and dilations.
