A figure has a 30 degree angle located at the point (-6,-8). What is the coordinate point for this angle when the figure is translated (x + 4, y - 1)?
A. (6,8)
B. (-2,-9)
C.(6, -8)
D. (-10, -7)
To find the coordinate point for this angle after the translation, we need to apply the translation vector (4, -1) to the given point (-6, -8).
Adding 4 to the x-coordinate and subtracting 1 from the y-coordinate:
x + 4 = -6 + 4 = -2
y - 1 = -8 - 1 = -9
Therefore, the coordinate point for this angle after the translation is (-2, -9).
The correct option is B. (-2, -9).
Which statement accurately describes what happens to parallel lines during a reflection?
A. They remain parallel
B. They become perpendicular
C. they intersect at an acute angle
D. They intersect at an obtuse angle
A. They remain parallel.
