@experimentX

OpenStudy (experimentx):

hmm .. it would be better to plot it. do you know what is slope and y intercept??

OpenStudy (experimentx):

do you know line of this form?? y=mx+c

OpenStudy (anonymous):

no :/

OpenStudy (anonymous):

mx+ b is what i learned

OpenStudy (experimentx):

okay .. okay ... what is m and what is b?

OpenStudy (anonymous):

m is slope

OpenStudy (anonymous):

b is the y-intercept

OpenStudy (experimentx):

hmm ... can you show me intercept on graph??

OpenStudy (anonymous):

yikes....nope

OpenStudy (anonymous):

please help!!!!

OpenStudy (anonymous):

okay:)

OpenStudy (experimentx):

okay ... you draw intercepts of f(x) and g(x)

OpenStudy (anonymous):

okay

OpenStudy (anonymous):

I'm not allowed to insert a graph into the question though

OpenStudy (anonymous):

how do i compare and contrast?
