Algebra 1.List #4

ordered pair

A pair of numbers that represent an individual point in a coordinate system, typically written in the format (x, y). 'x' is the horizontal value and 'y' is the vertical value.

x-axis

The horizontal axis in a coordinate system, which represents the value of 'x' in an ordered pair.

y-axis

The vertical axis in the coordinate system, representing the value of 'y' in an ordered pair.

horizontal line

A straight line that runs from left to right.

vertical line

A straight line that runs up and down, representing constant 'x' values in a coordinate system.

coordinate plane, grid, graph

A two-dimensional surface formed by the intersection of the x-axis and y-axis, dividing it into four quadrants, where ordered pairs can be plotted.

slope

The measure of the steepness of a line, often represented as the ratio of the rise (vertical change) over the run (horizontal change) between two points on the line.

solution to a linear equation

A pair of values (x, y) that satisfies the equation when substituted into it.

Linear Equation

An equation that models a straight line on a coordinate plane, typically expressed in the form y = mx + b.

Independent Variable

A variable that represents a quantity that is being manipulated in an experiment or equation, typically plotted on the x-axis in a graph.

Dependent Variable

A variable whose value depends on the value of the independent variable in a function or equation. It is typically represented on the y-axis in a graph.
