Question

Triangle ABC lies on the coordinate plane with vertices located at A(7,6), B(-3,5), and C(-4,9). The triangle is transformed using the rule (x,y) -> (2x,y-3) to create triangle A'B'C'. Select all possible answers for the vertices of triangle A'B'C'.
Question 1 options:

(14,3)


(9,3)


(-6,10)


(-8,6)


(-6,2)

Answer 1

The correct options are (a) , (14,3) , (d), (-8,6) and (e) , (-6,2)

By concept of translation, the coordinates of new triangle A'B'C' are given as follows:

A' (14, 3), B' (-6,2), C (-8, 6).

What is a translation?

A translation can be define or represented by a change in the graph of a function, which are done by the means of operations such as multiplication, addition or subtraction either in it’s range(i.e. the values of y) or in it’s domain(i.e. the values of x). Examples are compression of points or shifting  left right or bottom up, stretching and reflections over the axis that is the x-axis or the y-axis, or rotations around the origin.

For the given question, the translation rule is given as follows:

(x , y) -> (2x, y-3).

Applying the rule to each point of triangle, we have that:

A': (2(7), 6-3) = (14, 3).

B': (2(-3), 5-3) = (-6, 2).

C': (2(-4), 9-3) = (-8, 6).

Thus, the coordinates of triangle formed i.e. A'B'C' are given as follows:

A' (14, 3), B' (-6,2), C' (-8, 6).
