Which would be best to graph for someone who can't graph well ? Group 1 : y=-3/2x+4 -3x+2y=8 Group 2 : y=-2/3x-2 -2x+3y=-6 Group 3 : y=-1/3x+3 -x+3y=9 Group 4 : y=-1/6x+5 -x+6y=30

I suggest graphing it online and see which one you can draw better :)

Well there are different things I have to do after I pick a group. :I & I'm terrible at Slope ..

Slope is basically the change in y over change in x. I can't tell you which is easier for that.

*cries internally* I know that , but I mean I don't understand how to get the slop - intercept form .. :(

Oh hmm. Well, do you need it from the graph drawn or from calculation?

1. Choose one of the groups of equations from the table below. Indicate which group you choose in your word processing file. 2.Type the first equation from the group you selected and identify the slope and the y-intercept of the equation. 3.Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences. 4.Type the second equation from the group you selected and change the equation into slope-intercept form. Be sure to show all of your work. Identify the slope and y-intercept of the equation. 5.Describe how you would graph this line using the slope-intercept method. Be sure to write in complete sentences. 6.In a paragraph of at least three sentences, explain how the graphs of the two equations in your group are the same and how they are different. Be sure to use complete sentences.

Ah so you don't need to graph, only calculate. Well, look at the equations. You are given y in terms of x. If you want the y-intercept, what would the x value be. Put that into the equation and you get the y-intercept. The slope can be plucked from the equations themselves. Or, here's something from the internet(Google helps a lot): "I think the most useful form of straight-line equations is the "slope-intercept" form: y = mx + b This is called the slope-intercept form because "m" is the slope and "b" gives the y-intercept. (For a review of how this equation is used for graphing, look at slope and graphing.)" http://www.purplemath.com/modules/strtlneq.htm

I'm not sure which one to use though ? I have to graph something because part 2 says " Scan your graph " .
