1.D (-3,-3) 2. A(3,3)3.C(-2,-4)Reflection across X-axis changes sign of Y -coordinate Reflection across Y-axis changes sign of X-coordinate

If a point is reflected in a mirror, the reflection of the point appears on the other side of the line(mirror) wth an equal distance of the point from the mirror.1. Refection of the point (-3,3) across x-axis :In this the x-axis is compared with the mirror, so the image appears at equal distance from the x-axis in the other side. So, the image of the point (-3,3) across x-axis will be (-3,-3)The correct answer is : D (-3,-3)2.Refection of the point (-3,3) across y-axis : In this the y-axis is compared with the mirror, so the image appears at equal distance from the y-axis in the other side. So, the image of the point (-3,3) across y-axis will be (3,3)The correct answer is : A (3,3)2. The image of the given trapezoid ABCD with coordinates A(-4,5), B(-2,4), C(-2,2), D(-4,1). The reflection image in x-axis will be the trapezoid A'B'C'D' having the coordinates A'(-4,-5), B(-2,-4), C(-2,-2), D(-4,-1).So, the correct answer for the coordinates of the image of point B will be : C (-2,-4)
