Question

A translation function is defined by the rule (x, y) → (x + 2, y - 5).

Which choice will be the image of the point (3, 6) under this translation?

  1. (5, 1)
  2. (5, 11)
  3. (1, 1)
  4. (-1, 11)

hintHint:

The translation is the act of moving a shape or a figure from one location to another. A figure can move in translation up, down, right, left, or anywhere else in the coordinate system. Only the object's position changes during translation; its size stays the same.
We have given a point (3, 6), we have to find the image for the translation function of (x, y) → (x + 2, y - 5) when it is applied.

The correct answer is: (5, 1)


    Now as we said that in translation, a point or a figure can move up, down, right, left, or anywhere else in the coordinate system. Any point can be located using a Cartesian coordinate system or coordinate system, and that point can be displayed as an ordered pair (x, y) known as Coordinates.
    We have a point (3, 6). The translation function is (x, y) → (x + 2, y - 5).
    We have to shift the points from the given coordinates to (2, -5).
    Let's consider (3, 6), we have to shift 2 units to right and 5 units down.
    (3, 6) -------  (3+2, 6-5)
    (3, 6) -------  (5, 1)
    So the algebraic representation will be: (5, 1)

    In this question, we used the concept of translation and found out the points according to the condition given. We also understood the concept of the cartesian system and the coordinates. In translation, only the position of the object changes, its size remains the same. The algebraic representation will be: (5, 1).

    Which of the following figures has multiple lines of symmetry (more than one line of symmetry)?

    If a line can be drawn separating a figure into two identical pieces, the figure possesses line symmetry. The path is known as a symmetry line. A figure might only contain one line of symmetry, two lines of symmetry, or none at all. So here the figure 4 has more than 1 line of symmetry.

    Choose the image which shows reflective symmetry.

    In mathematics, reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry is symmetry with respect to a reflection. That is, a figure which does not change upon undergoing a reflection has reflectional symmetry. In 2D there is a line/axis of symmetry, in 3D a plane of symmetry.
