The vertices of a triangle are P(- 4,1) O(- 2, - 8) and R(8, - 1) What are the vertices of the image reflected across the x- axis?
(1 point)
A.P(- 4,- 1) 4,-1), Q(- 2, 8) ,and R| R(8, 1)
B.P(4,- 1) , Q(2, 8) and R(- 5, 1)
C.P(4,1) O(2, - 8) and R(- 8, - 1)
B.P(- 4,1) O(- 2, - 8) , and R(8, - 1)
The vertices of the image reflected across the x-axis would have the same x-coordinates, but the y-coordinates would be negated.
So the vertices of the image would be:
A. P(-4, -1), O(-2, 8), and R(8, 1)
To reflect a point across the x-axis, we change the sign of the y-coordinate while keeping the x-coordinate the same.
The original vertices are:
P(-4, 1)
O(-2, -8)
R(8, -1)
To reflect across the x-axis:
- P(-4, 1) becomes P(-4, -1)
- O(-2, -8) becomes O(-2, 8)
- R(8, -1) becomes R(8, 1)
Therefore, the vertices of the image reflected across the x-axis are:
A. P(-4, -1)
O(-2, 8)
R(8, 1)
