Question

Isabella painted a water colour design on gridpaper. Some of the points were at A (-4, 8),B (-2, 8), C(-1,6), D (-2, 4), E (-4, 4), andF (-5, 6). She folded the paper along y = 3 toreflect the design. The image points are A', B',C', D', E', and F.a) Draw the line y = 3. (Hint: The x-axisis the line y = 0. For which line is they-coordinate 3 for every point?)b) Determine the coordinates of A', B',C.D', E', and F'.c) Draw the image, and label A', B', C',D', E', and F'.y8-7-€6-4.32-5•1 C

Answer 1

EXPLANATION

Drawing the line y=3 give us the following graph:

Reflecting over the axis y=3 give us the following image points:

A' = (-4,2)

B' = (-2,-2)

C' = (-1,0)

D' = (-2,2)

E' = (-4,2)

F'= (-5,0)
