Understanding Graphs and Slope

These flashcards cover key concepts related to understanding graphs and slope based on the lecture notes.

Graphs

Visual representations of data showing relationships between variables.

Slope

A measure of the steepness or angle of a line representing the rate of change between two variables.

Independent Variable

The variable on the x-axis that is manipulated or changed.

Dependent Variable

The variable on the y-axis that responds to changes in the independent variable.

Cartesian Coordinate System

A two-dimensional coordinate system used to define the position of points using pairs of numbers.

Quadrants

The four sections of a Cartesian coordinate system, defined by the signs of the x and y values.

Graph of One Variable

Graphs that showcase a single variable, like bar graphs and pie charts.

Graph of Two Variables

Graphs that show the relationship between two variables.

Y-Intercept

The point where a line crosses the y-axis, indicating the value of y when x is zero.

Rise and Run

The vertical and horizontal changes used to calculate the slope of a line.

Intersecting Equations

The point where two equations meet on a graph, revealing common values for the variables.

Data Visualization

The graphical representation of information and data to enhance comprehension.
