Point A(4,2) is translated according to the rule (x,y)-->(x+1,y-5) and then reflected across the y axis
a)In which quadrant of the coordinate plane is point A located?
b) What are the coordinates of translated point A'? in which quadrant of the coordinate plane is point A' located?
c)What are the coordinates of the reflected point A"? In which quadrant is point A" located?
I just want to know what the apostrophes mean after the "point A"
(4,2) is in the first quadrant
(5, -3) is in fourth quadrant, lower right
across y axis, same y, change sign of x
(-5,-3) quadrant III
A(4,2) gives the coordinates of a point labeled A
From the origin, it is 4 units to the right and 2 units up .
reflection:
(x,y) ---> (x+1,y-5)
(4,2) ---> (5,-3)
reflection across y-axis
(x,y) --> (-x,y)
(5,-3) --> (-5,-3)
