What is a function?

A function is a relationship that takes an input (x) and produces a unique output (y) based on a specific rule.

What is a linear function?

A linear function can be represented by a straight line on a graph. It has a constant rate of change (slope).

What is slope?

The slope of a line tells you how steep it is. A positive slope indicates an upward trend, and a negative slope indicates a downward trend.

What is the x-axis?

A function's input value is plotted on the x-axis, and the corresponding output value is plotted on the y-axis.

What is the y-axis?

A function's output value is plotted on the y-axis, and it corresponds to the input value on the x-axis.

What is a proportional relationship?

A proportional relationship is a special kind of linear function where the ratio between the input and output values is constant.

What is the y-intercept?

The y-intercept is the point where a line crosses the y-axis. It represents the output value when the input is zero.

What is slope-intercept form?

The equation of a line can be written in slope-intercept form (y = mx + b), where m is the slope and b is the y-intercept.

What is a solution to an equation?

To solve an equation with a variable (like x), we need to find the value that makes the equation true. This is the solution.

What are similar figures?

Similar figures have the same shape but different sizes. Their corresponding sides are proportional, meaning they have the same ratio.

What is the Pythagorean theorem?

The Pythagorean theorem states that in a right triangle, the square of the hypotenuse (longest side) is equal to the sum of the squares of the other two sides.

What is volume?

The volume of a three-dimensional shape is the space it occupies. We measure it in cubic units.

How can data be represented?

Data can be represented in various ways, like bar graphs, histograms, or scatter plots. Choosing the right representation depends on the type of data and what we want to show.

What is probability?

Probability measures the likelihood of an event happening. It is a number between 0 and 1 (or 0% and 100%)

What is the difference between expressions and equations?

Expressions are combinations of numbers, variables, and operations, while equations include an equal sign. Equations show that two expressions are equal.
