No idea what 🔼 means, but it looks like a reflection or two is involved.
across the x-axis: (x,y)→(x,-y)
across the y-axis: (x,y)→(-x,y)
The vertices of a triangle are P(1,4), Q(-7,7), and R(2,-6). Name the vertices of R y=x(🔼PQR).
A. P’(4,-1), Q’(7,7), R’(-6,-2)
B. P’(-4,1), Q’(-7,-7), R’(6,2)
C. P’(4,1), Q’(-7,7), R’(-6,2)
D. P’(-4,-1), Q’(-7,7), R’(6,-2)
