Playing with Equations to Solve Problems Date: 09/16/2003 at

an equation I need to give the geometric property common to all
lines in the family x - ky = 1 I know that the answer is that
all lines in this family have an x-intercept at x=1 but I am
totally clueless about showing why this is the case. At first I
thought that using the double-intercept equation (x/a) + (y/b) =
1 would work but I couldn't get it in the correct form. Then I
tried to solve for x and y and got x = 1 + ky and y = (-1/k) +
(-x/k) but now I do not know what to do with this. So I was
wondering if you knew how to go about solving this? Date:

state the geometric property of an equation Hi, Mara. I don't
think there is any method you can use to solve this sort of
problem without a lot of thinking and testing. Let's see how I
personally would approach it (as well as I can construct it,
considering that I know the answ
