Answer:
u'= -8,3
r'= -4,3
t'= -8,10
s'= -4,10
Explanation:
first you have to do jot down your point on a piece of paper.
u= 3,8
r= 3,4
t= 10,8
s= 10,4
you need to move from quadrant 1 to 2
so you know in quadrant 2 all the x values are negative and all the y values are positive.
so when you are writing your answers your x values must be negative.
this is a simple trick.
all you have to do is switch your numbers and put a negative sign in all the x values like so.
u= 3,8
r= 3,4
t= 10,8
s= 10,4
u'= -8,3
r'= -4,3
t'= -8,10
s'= -4,10
now if you see what I did I switched the x and y values from the original points and put a negative sign on all my x values.
And boom your answer!
