In the graph below, point d is reflected across the y axis. what are the coordinates of its image ?

Generally, whenever a point (x,y) is reflected across the y axis, the y coordinate stays the same and the sign of x coordinate changes.

So changes to .

Point D in the diagram shown has coordinates . According to the rule, the x-coordinate, 3, will change to -3 and the y-coordinate, -1, would stay the same.

Hence, our image of D after the reflection about y-axis would have coordinates .

ANSWER:

answer: 43/157

this is the answer and if you try to prove me wrong your a meanie

answer: 2530

hope this
