Find the point of intersection between y=2-(1/2)x and y=1+ax. (a=alpha sign). You answer will be a point in the xy plane whose coordinates involve the unknown a .
My work so far:
I set the two equations equal to each other because they intersect.
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!
