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.
Why don't you just try drawing it? :huh: Surely the answer will be clear then :)
i need to know if there is something i can add or subtract to the x or y number in this case
(4, 7) (I think)
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
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't x=1 a vertical line parallel to the y-axis?Quote:
