The key idea of the transformation called a reflection is

the object moves the plane a certain angle measure
the object moves in a straight line movement
the object and its image have opposite orientations
the rotating of a plane about a fixed point

The object and its image have opposite orientations

Step-by-step explanation:

A reflection is a type of rigid transformation in which the preimage is flipped across a line of reflection to produce the image, such that the figure and its image have opposite orientations.

Since, it preserves distance.

Therefore, the points of the image have the same distance from the line as the points of pre-image on the opposite side of the line.

Hence, the right option is "the object and its image have opposite orientations".

Point of Interception will be (7,8/3)

Step-by-step explanation:

Point of intersection of two graph equations mean to find the value of x and y.

So,

20x - 15y = 100(1)

3x - 6y = 5(2)

Multiplying (1) with 3 and (2) with 20.

{20x - 15y = 100} * 3

= 60x - 45y = 300__(3)

&

{3x - 6y = 5} * 20

= 60x - 120y = 100_(4)

Subtracting (4) from (3),

60x - 45y = 300

60x - 120y = 100

-+-

75y = 200

y = 200/75 = 8/3

Substituting the value of y in (2)

3x - 6(8/3) = 5

3x - 16 = 5

3x = 5+16 = 21

x = 21/3 = 7

x = 7

The coordinates of interception will be x-intercept = 7 & y-intercept = 8/3.
