Success Criteria

• Given an equation, I can make a table and graph

• Given a graph, I can make a table and write the equation

Notebook: Starting with an Equation

Example Make a table to graph

 $y=2x+1$  
(we will graph it on the next slide)

Now plot our points neatly on a graph:

Using our table

Notebook: Starting with a Graph

Given the graph, make a table and write the equation

Multiple Choice

Select the equation for the graph

• y = x

• y = 4x

• 4 = x + 4

• y = x + 3

Multiple Choice

Select the equation for the graph to represent the cost of each ticket. X represents the # of tickets and Y represents the cost

• Y = $2X + $2.00

• Y = $X + $1.25

• Y = $2.5X

• Y = $1.50X
