Question

A triangle has vertices at r(1,1), s(-2,-4) and t(-3,-3). The triangle is transformed according to the rule r0,270.what are the coordinates of s?

Answer 1

Answer:

D. (4, –2)

Step-by-step explanation:

We are given that,

Triangle RST have vertices R(1, 1), S(–2, –4), and T(–3, –3).

It is given that the function is rotated by 270° about the origin counter-clockwise

This transformation changes the co-ordinates (x,y) to (y,-x).

Thus, the co-ordinates of S' will be obtained by changing the co-ordinates of S = (-2,-4) by the above rule.

Hence, the co-ordinates of S'= (4,-2).

So, option D is correct.
