Question

Line segment XY begins at (-6,4) and ends at (-2,4). The segment is reflected over the x-axis and translated left 3 units to form line segment X'Y'. Enter the lenght, in units, of line segment X'Y'

Answer 1

Line segment XY begins at (-6,4) and ends at (-2,4); XY is reflected over the x-axis and translated left 3 units to form line segment X'Y' which has a length of 4 units.

What is an equation?

An equation is an expression that shows the relationship between two or more numbers and variables.

Line segment XY begins at (-6,4) and ends at (-2,4). Hence:

$XY=\sqrt{(4-4)^2+(-2-(-6))^2}=4\ units$

XY is reflected over the x-axis and translated left 3 units to form line segment X'Y'. Hence:

XY = X'Y' = 4 units

Line segment XY begins at (-6,4) and ends at (-2,4); XY is reflected over the x-axis and translated left 3 units to form line segment X'Y' which has a length of 4 units.
