Question

i) Plot points A (0, 3), B (2, 3), C (3, 0), D (2, -3), E (0, -3)
(ii) Reflect points B, C and D on the y axis and name them as B', C' and D'
respectively.
(iii) Write the co-ordinates of B', C' and D'.
(iv) Write the equation of line B' D'.
(v) Name the figure BCDD'C'B'B

Answer 1

for part(i) and (ii) refer to the above picture.

part (iii):- B'(-2,3). C'(-3,0). D'(-2,-3).

part (iv):-

slope of line B'D'= -3-3/-2+2

= -6/0

= -6.

mid point of the line B'D' according to the graph is =(-2,0)

•°• equation of the line= y - 0 = -6(x-(-2))

= y - 0= -6(x+2)

= y - 0= -6x -12

= y+6x+12= 0

= 6x+y+12=0.

part (v):- The figure is hexagon.

hope it helps you.......... .
