My work so far:

I set the two equations equal to each other because they intersect.

1+ax=2-(1/2)x

and I got,

(-1)/( (-1/2)-a )=x

how do I find y?

Do I plug in what i found for x into one of the equation? Please help!

**drwls**, Thursday, October 8, 2009 at 7:30pmy = 2 - x/2

y = 1 + ax

0 = 1 - x/2 - ax

x(a + 1/2) = x(2a+1)/2 = 1

x = 2/(2a+1)

y = 1 + 2a/(2a+1)

You started out OK, but should have simplified the equation for x and used it to derive an equation for y.
