Answer:
The coordinates of point B are (4,3)
Step-by-step explanation:
Plot point A on a grid
Find the y-axis (vertical line)
Count how many units it take for you to get from point A to the y-axis
Then, from the spot on the y-axis you landed on, count the same number of units to get point B
OR
Look at the quadrants. The quadrant you are in is number two. The coordinates will always be (-,+)
If you cross the y-axis you'll be in quadrant number one. These coordinates will always be (+,+)
Since you know the numbers HAVE TO STAY THE SAME during a reflection. Then the only answer you can get it (4,3)
