The point (2, –4) is reflected across the line y = –1. What are the coordinates of the image?
schepotkina [342]

ANSWER

The coordinates of the image are (2,2)

EXPLANATION

The mapping for a reflection across the line y=k is :

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

We want to find the image of the point (2,-4) after a reflection in the line y=-1.

In this case k=-1.

(2, - 4)\to (2,2( - 1)- - 4)

This simplifies to,

(2, - 4)\to (2, - 2 + 4)

(2, - 4)\to (2, 2)

Hence the image is (2,2)

Answer:

D) 1188 in.^2

Step-by-step explanation:

33×36 is 1188, the triangle on the side doesn't matter because it can be used to make the rectangle a whole rectangle, which means that the only important numbers are 33 and 36 multiplied to find the area, which is 1188^2.
