​Review Graphing a Line (y=mx+b)

Multiple Choice

Graph $$y=-\frac{1}{2}x-3$$  

Multiple Choice

Graph $$y=x+4$$   

Multiple Choice

Graph $$x=2$$    

Multiple Choice

To graph $$-6x-3y=15$$  , we must first get it in slope-intercept form.

• $$y=2x+5$$  

• $$y=2x-5$$  

• $$y=-2x+5$$  

• $$y=-2x-5$$  

Multiple Choice

We have converted $$-6x-3y=15$$   to $$y=-2x-5$$  .

Now it's time to graph it.

Multiple Choice

To graph $$-5x+5y=25$$   , we must first get it in slope-intercept form.

• $$y=x+5$$   

• $$y=-x+5$$   

• $$y=5x+5$$   

• $$y=-5x+5$$   

Multiple Choice

We have converted $$-5x+5y=25$$    to $$y=x+5$$   .

Now it's time to graph it.

Multiple Choice

To graph $$x+2y=8$$    , we must first get it in slope-intercept form.

• $$y=\frac{1}{2}x+4$$    

• $$y=\frac{1}{2}x-4$$    

• $$y=-\frac{1}{2}x+4$$    

• $$y=-\frac{1}{2}x-4$$    

Multiple Choice

We have converted   $$x+2y=8$$    to $$y=-\frac{1}{2}x+4$$    .

Now it's time to graph it.
