Question

Someone please please help me with this geometry quesiton

Answer 1

what is the image of the point (-5,-9) reflected across the y-axis

Answer 2

flipping over the y-axis will change the sign on the x coordinate

Answer 3

so the answer will be (5,-9)?

Answer 4

graph it and see

Answer 5

yeah, flip means 'perpendicular to' the y-axis

Answer 6

for a single point

Answer 7

aha... and how about this.. what is the image of the point (-2,-4) relfected across the line y = x

Answer 8

reflecting something perpendicularly over y=x, also called the inverse if it exists

Answer 9

here, the signs change on both y and x

Answer 10

i see I understand now :) !!!

Answer 11

sorry , forget that

Answer 12

oh

Answer 13

it looks like this, perpendicular to th eline y=x

Answer 14

just change y and x around

Answer 15

so (2,4)?

Answer 16

any point reflected over the line y=x, just change x and y like that

Answer 17

graph the points

(1,1)
(-1,1)
(-1,-1)
(1,-1)

notice reflecting from one to the other over each axis, how the signs change

Answer 18

you good on that, or

Answer 19

ok so the answer is (-4,-2)

Answer 20

reflection over x-axis --- change sign on y coordinate

reflection over y-axis ----change sign on x coordinate

reflection over y=x -----swap coordinates (y,x)
