Triangle XYZ is reflected about the y-axis. What are the coordinates of X’?
Dominik [7]

Just flip the signs of co-ordinates by using formula y=>-y

  • Make sure to do this with y only as it has been reflected to y axis

\\ \ast\bull\rm\longmapsto Z(-5,-4)\implies Z'=(-5,-(-4))\implies Z'=(-5,4)

\\ \ast\bull\rm\longmapsto Y(-3,-4)\implies Y'=(-3,-(-4))\implies Y'=(-3,4)

\\ \ast\bull\rm\longmapsto X(-5,-1)\implies X'=(-5,-(-1))\implies X'=(-5,1)
