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

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

An example of a plotted graph

Let's calculate the slope

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

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