A line containing the points minus 2, 3 and 2, 3 is reflected across the access x how long is the reflect in line three units for a week units Infinity long not enough information
To find the length of the reflection line, we need to determine the distance between the two points before and after reflection.
Before reflection:
Point A: (-2, 3)
Point B: (2, 3)
The distance between these two points is given by the formula:
distance = √[(x2 - x1)^2 + (y2 - y1)^2]
distance = √[(2 - (-2))^2 + (3 - 3)^2]
distance = √[(4)^2 + (0)^2]
distance = √[16 + 0]
distance = √16
distance = 4
After reflection across the x-axis:
Point A' : (-2, -3)
Point B' : (2, -3)
The distance between these two points is the same as before since it is a reflection across the x-axis. So, the length of the reflection line is 4 units.
