Introduction to Graphs, Graphing Equations and Inequalities:


A graph is depicted in diagrammatic form as asset of dots for the vertices joined by line or curve. It is a representation of set of object where some object are connected by the links. Vertices are the interconnected objects.

Types of graphs:

Distinction in terms of the main definition

  • Undirected graph
  • Directed graph
  • Mixed graph
  • Multi-graph
  • Quiver
  • Simple graph
  • Weighted graph
  • Half-edges, loose edges

Important graph classes

  • Regular graph
  • Complete graph
  • Finite and infinite graphs
  • Graph classes in terms of connectivity
  • Category of all graphs

Graphing with slope-intercept:

y=(-1)/3 x+2

Graphing with slope-intercept

1. Start by graphing the y-intercept (b = 2).

2. From the y-intercept, apply “rise over run” using your slope. rise = 1, run = -3

3. Repeat this again from your new point.

4. Draw a line through your points.

Graphing Linear Inequalities:

A Linear Inequality is like a Linear Equation (such as y = 2x+1), but it will have an Inequality like <, >, ≤, or ≥ instead of an =.

How to Graph a Linear Inequality

First, graph the "equals" line, then shade in the correct area. There are three steps:

1. Rearrange the equation so "y" is on the left and everything else on the right.

2. Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)

3. Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than " (y< or y≤).

Example for inequality:

Equation: y≤ 2x-1

The inequality already has "y" on the left and everything else on the right, so no need to rearrange Plot y=2x-1

Example for inequality
