Question

Rotate the following figure 90° counterclockwise about the origin: l: (-3,-4), J: (-4, 0), K: (-3, O), L: (0, -2)

Answer 1

Let's begin by identifying key information given to us:

`I(-3,-4),J(-4,0),K(-3,0),L(0,-2)​`

We are to rotate the figure 90 degrees counterclockwise about the origin. The transformation is mapped by the formula:

`\begin{gathered} A\mleft(x,y\mright)\rightarrow A^(\prime)\mleft(-y,x\mright) \\ I(-3,-4)\rightarrow I^(\prime)(4,-3) \\ J\mleft(-4,0\mright)\rightarrow J^(\prime)(0,-4) \\ K\mleft(-3,0\mright)\rightarrow K^(\prime)(0,-3) \\ L\mleft(0,-2\mright)\rightarrow L^(\prime)(2,0) \end{gathered}`
