Introduction to
Graphing: Linear Equations

Slide 1 - Tekstslide

Quick review
  • The x axis and the y axis  
  • ( x , y ) v.s. y/x
  • Slope is y1 - y2/ x1 - x2
  • Graphs always move to the right, whether positive or negative

Slide 2 - Tekstslide

How to Graph
When you graph linear equations, there are two important things to remember:
1. Structure
y = mx + b
2. Rise/Run or rise over run

Slide 3 - Tekstslide

An example of a plotted graph
Let's calculate the slope

Slide 4 - Tekstslide

Now, let's try to graph a few!
  1. y = x + 3
  2. y = 1/2 x -1
  3. y = -3/4 x 
  4. y = 2/3 x - 4

Slide 5 - Tekstslide

Write the y = mx + b equation for this linear graph
