What function equation is represented by the graph? http://prntscr.com/dg6mgj

OpenStudy (royalranger):

y = mx + b

OpenStudy (caozeyuan):

the graph has a positive slope and negative intecept

OpenStudy (caozeyuan):

so C is the only answer

OpenStudy (yuii):

Are you sure?

OpenStudy (royalranger):

b = -3 and m = 1/4 therefore: y = 1/4x - 3

OpenStudy (caozeyuan):

yes, and the trick is that you dont even need to know what exactly is the slope and intercept, you just need to figure out if they are postivite ornegative

OpenStudy (yuii):

Okay, thank you both.
