Question

what composition transformation rule has △lmn, l(8,3), m(4,6), and n(5,9) map onto △lmn, l(-10,-3), m(-6,0), and n(-7,3)? (1 point)

o a rotation of 270 degrees clockwise and a move right by 2 and up by 6

o a reflection over the y - axis and a move to the left by 6 and down by 2

o a reflection across the x - axis and a move to the right by 2 and down by 6

o a reflection over the y - axis and a move to the left by 2 and down by 6

Explanation:

Step1: Test Option d on L(8,3)

Reflect over y-axis: (-8,3). Translate left 2, down 6: (-8-2, 3-6)=(-10,-3)=L'.

Step2: Verify M(4,6)

Reflect over y-axis: (-4,6). Translate left 2, down 6: (-4-2,6-6)=(-6,0)=M'.

Step3: Verify N(5,9)

Reflect over y-axis: (-5,9). Translate left 2, down 6: (-5-2,9-6)=(-7,3)=N'.

Answer:

d. a reflection over the y-axis and a move to the left by 2 and down by 6
