positive 7 and i cant figure out the other number

7 is the y-coordinate. From point C, follow the line down to the x-axis. What number is that?
anonymous
  • anonymous
i got positive 3
anonymous
  • anonymous
right, so C is (3, 7)

can you put where C' would be after the reflection?
anonymous
  • anonymous
on y or x axis?
anonymous
  • anonymous
y
anonymous

im not sure on how to do that here
anonymous
  • anonymous
ok, well which quadrant do you think it'd be in?
anonymous
  • anonymous
it will be negative i think
anonymous

Basically all you have to do is change the sign on the x-coordinate of C to get C'|dw:1441402979571:dw|

ohhhh makes sense now

good. So what would be the coordinates for C' ?
anonymous
  • anonymous
7 and -3?
anonymous
  • anonymous
yes
anonymous
  • anonymous
ohh so only the y coordinate changes
