errrr, assuming there is a slope... slope = (-59 - 13)/(13-1) slope = -6 y = -6x + c 13 = -6(1) + c c = 19 To check y = -6x + 19 y = -6(13) + 19 y = -59 Not sure what grade this is sorry...

I don't know what objects have the same volume. But just because their volume is the same that does not mean the mass is. For example : Density = Mass/Volume Lets say there are objects both with volume of 10 Volume = Mass / Density First object is 1000 in mass and 100 in ...
