Hey can someone please explain to me how to figure out how to match slope fields to their graphs without the use of a calculator? for problem such as these: y'=-y b) y'=x-y c) y'=1/y

    you simply have to plot the slope/vector representations on a piece of paper... right?

    well, my guts says to connect the slopes from end to end to determine what they look like at the given points.... for example: y'=-y

    not exactly, but I do know that when y'=0 ; you have a high or low point, or even an inflection. You determine that by seeing if the sign of the slope changes; then its a high or low; or stays the same, then its an inflection....

    by finding the zeros, you mean to determine f(x) from the f(x) = 0 information?

    hmm ... that doesnt look familiar to me, id wanna say that that simply means the y = 0 but without the proper context its hard to say..
