oh, sorry i had 2 step away, haha yes, I know. I'm not THAT lost.

amistre64 · Answer

;)  whew!!

since x= represents a vertical line then,
        y= represents a horizontal line

we need a "y="  such that it passes thru the point (2,1).

mkay

amistre64 · Answer

since the points are defined as (x,y)
                                              (2,1), tells us that y=1

anonymous · Answer
