Question

A carnival ride is drawn on a coordinate plane so that the first car is located at the point (30,0). what are the coordinates of the first car after a reputation of 270° about the origin?

Answer 1

Let's begin by listing out the information given to us:

The first point is (30,0)

The carnival ride undergoes a 270° rotation

The general rule for rotation over 270° is given by: (x, y) = (y, -x)

`\begin{gathered} (x,y)=(y,-x) \\ A(30,0)=A^(\prime)(0,-30) \end{gathered}`

A (30,0) = A' (0,-30)
