Giving medal!!! An artist designed a badge for a school club. Figure ABCD on the coordinate grid below shows the shape of the badge.
The badge is enlarged and plotted on the coordinate grid as Figure JKLM with point J located at (1, -6) and point M located at (3, -2). Which of these could be the possible coordinates for a vertex? (1 point) (-1, -6) (5, -2) (6, -6) (7, -2)

The two points (J and M) are representing the points A and D that have been relocated and dilated by a factor of 2. Do you see that?
yea
Point M is at (3, -2) now you can locate a vertex that represents the old point C. In the original figure ABCD you can see that point C is on the same y axis as point A and located one x division to the right. Thus, the equivalent location for the new figure would be at for the x we would now use 2 x divisions (dilated by a factor of 2) to the right giving us an x value of 5, while the y value would remain the same , or -2. The vertex would be then one of your choices.
k
so would it be b?
Now that is one vertex as you can see there are 4 vertex, yes that is correct, and the only good choice, the other vertex is at (7, -6) and the other 2 vertices are given (points J and M)
I hope you followed this explanation, I kinda get the feeling you did.
so i just wanna ask its not b? i was thinking c?
No you had it correct. that was the best answer, stick with it.
okay thanks :D
The other 3 vertices are (1, -6) (3, -2) and (7, -6) and they are not options.
alright thanks :D
