Question

In a certain year, the amount A of garbage in pounds produced after t days by an average household is given by A=7.5t. a.) Graph the equation t>0. b.)How many days days would it take the household to produce 100 pounds of garbage.

anonymous · Answer

100=7.5(t)
so t=13.3333 so 14 days

I am having problems trying to graph this on my assignment, Where would the points actually be? Or what points would the line be on?

anonymous · Answer

start at the origin... it has a positive slope and just plot when x=1, x=2, x=3 x=4, etc.
when x=1 then y is 7.5 (1,7.5)
x=2 then y is 15 so (2, 15)
just multiply the x by 7.5 and get your y coordinate.

Ok, I thought that's what your line looked like but wanted to make sure. Thanks again. How do you give out medals on here?

anonymous · Answer

or if you have a graphing TI calculator, you can put the equation into the y= function, then hit the 2nd graph button and get your table, and you have all the points you need there too.

@zonazoo, how do you even get the points toinput it , for example say it is 250 pounds of garbage and A=7.5, How would I graph that?
