Question

triangle TAB is located at T(2,3), A(1,1) and B(4,-3). Plot the shape, reflect this over the y-axis, then translate the image by rule (x,y) to (x+2, y- 1). record the coordinates of the images in the provides spaces.

Answer 1

reflect over the y-axis

$T_1(2,3)\to T_2(-2,3)$

$A_1(1,1)\to A_2(-1,1)$

$B_1(4,-3)\to B_2(-4,-3)$

translate the image by rule (x,y) to (x+2, y- 1)

$T_2(-2,3)\to T_3(0,2)$

$A_2(-1,1)\to A_3(1,0)$

$B_2(-4,-3)\to B_3(-2,-4)$
