41. What is the image of O(- 3, - 2) after two reflections, first across the line y = - 5 , then across the line x = 1 ? (1 poin

liberstina [14]

Answer:

D(5,-8)

Step-by-step explanation:

The given point is (-3,-2)

When we reflect in the line y=k, we use the rule (x, 2k-y)

This implies that:

$(-3, - 2)\to (-3, 2*-5--2)$

$(-3, - 2)\to (-3, - 8)$

When we reflect in the line x=k, we use the rule

$(x,y)\to (2k-x,y)$

Now we have x=1

This implies that:

$( - 3, - 8)\to (2 \times 1- - 3, - 8)$

$( - 3, - 8)\to (5, - 8)$
