I was wondering when you'd actually provide the graph ^_^
These are reflections, no?
they are product transformations
but yes, they're reflections i fguess
Well, first you work from right to left... what happens when you reflect the point across the x-axis (Rx) ?
it becomes negative, correct?
Not exactly... when you reflect across the x-axis, only the y-coordinate becomes negative, x stays the same.
So after Rx, your point is now...?
That's right. Now, we reflect across the other line, the line k.
It's hard to go into the nitty gritty details of what actually goes on in this reflection, but suffice it to say, reflecting across the line k (actually the line y = -x)
What happens to a point is that the two coordinates switch, and then both get multiplied by -1.
So, for instance, the point (3,-1), after being reflected across the line k, becomes...
--> (-1,3) [switch]
--> (1,-3) [multiply both by -1]
so now, you just do that to
and you'll be all set ^_^
ok! thanks! i think it would've confused me if you exexplained it the long way anyways! haha thank you! @terenzreignz
