Question

The vertices of square HIJK have coordinates H(−3, 2), I(−5, 2), J(−5, 4), and K(−3, 4). Square HIJK was transformed to produce square HꞌIꞌJꞌKꞌ, with coordinates Hꞌ(−3, −2), Iꞌ(−5, −2), and Kꞌ(−3, −4).

What are the coordinates of vertex Jꞌ?

Answer 6

@welshfella do u get it

Answer 7

note that the x coordinate of H and its image H' are the same but the y coordinate of H is 2 and y coordinate of H' is -2.

Answer 8

this means its a reflection in the x-axis

Answer 9

ok but the coordinates will be

Answer 10

sorry i dont understand what it says

Answer 11

the top x is the position of H
and bottom x is the position of H'

Answer 12

so the coordinate is 2 -3

Answer 13

its a similar story for the points I , I' , K and K'

so for J' the x coordinate will be the same and Y coordinate will be negative of y coordinate of point J

Answer 14

No - look at coordinates of point J

Answer 15

-5 4

Answer 16

actually i messed up the diagram the point should left of y axis...

Answer 17

ok

Answer 18

it doesn't matter the answer will still be the same
J = (-5,4) so J' = (-5, ?)

Answer 19

-4

Answer 20

right J' = (-5,-4)

Answer 21

thats the answer
