# Thread: Math Vacation Homework Help- Again Lol

1. i have a problem. It is as follows:

When point (-2,7) is reflected in the line x=1, the image is....
(1) (7,2)
(2) (-2,-5)
(3) (4,7)
(4) 0,7)

I need to know how to do it. If anyone can help with this, I have more without multiple choices. Thanks a lot guys.

2. Why don&#39;t you just try drawing it? Surely the answer will be clear then

3. i need to know if there is something i can add or subtract to the x or y number in this case

4. (4, 7) (I think)

5. Well, you reflect it through a line in x=1, which means it is a horizontal parallel with the X-ax.

You have another line with coordinates (-2,7). The Y cooridinate stays the same so you only have to look at x. -2 is how far away from 1? Add that number to 1 and you have your answer

6. another example i have is Find the image when reflected in line y= -2. The point is 1,4. does this mean that new y number is 4 and keep the x number. im confused...

Isn&#39;t x=1 a vertical line parallel to the y-axis?

I&#39;m getting a bit rusty
