Question

10. Parallelogram ORST with vertices Q12, -1), R(7, 1), S(6, -2), and T(1, -4): (a) Reflection: in the line y = x (b) Translation: (x, y)= (x - 3,y-7)I really just need Q and R

Answer 1

Q = (12,-1)

R= (7,1)

When reflecting a coordinate point (x,y) across the line y= x, the new coordinate is (y,x)

a)

Q'= (-1,12)

R'= (1,7)

b) Translation: (x,y) = (x-3, y-7)

Q´= (12-3,-1-7) = (9,-8)

R'= (7-3,1-7) = (4,-6)
