CHOOSING BEST GRAPHING METHOD

Math 8

2 of 23

 

Use the slope and the y-intercept to graph.

 

slope-intercept form

begin at the

y-intercept

move to get

more points

3 of 23

 

Use the x- and y-intercepts to graph.

 

standard form

y-intercept

set the opposite variable = 0

to find the intercept

x-intercept

 

 

4 of 23

Change to slope-intercept form

Use inverse operations to get y by itself on one side of the equation

Step 1: Move the x’s to the other side using the inverse operation

Step 2: Divide all terms by the coefficient in front of the y

Resulting equation should be in

so you can graph by beginning

at the y-intercept point and move using the slope to find subsequent points

Graph using any method you choose. Make sure to show points clearly, use a ruler, and extend the lines with arrows

 

 

 

 

Notice it is the exact same line

as graphed by intercepts

Option 2: Change to slope-intercept form

standard form

y-intercept will

be a whole number

x-intercept will be

a mixed number 😐

Graph using any method you choose. Make sure to show points clearly, use a ruler, and extend the lines with arrows

Option 1: Graph using intercepts is not simple

Graphing using intercepts is convenient when

both intercepts are

whole numbers, otherwise

you may want

to

change

to

slope

-intercept
