Question

If triangle PQR is plotted, it will have the following coordinates, P(-4,0),Q(4,2) and R(-2,4).If point R is translated 4 units right and 7 units down, what are the coordinates of P'Q'R'?Explain your answer.

Answer 1

For R the coordinates are ( -2,4)

For R' the coordinates are ( 2,-3)

because X is traslated 4 units to the right -2+4=2

and Y is translated 7 units down. 4-7= -3

Now calculate the same for P and Q

For P' the coordinates are (0,-7)

because -4+4=0 and 0-7=-7

For Q' the coordinates are (8,-5)

because 4+4=8 and 2-7= -5
