What point do you rotate across?
(0,0) Origion
What is Y=MX+B
Slope Intersept
Reflecting over the Y axis changes the
X Cordnate

(3, 0), (5, –3), (7, 1)
A pentagon’s vertices are translated by vector ⟨5,−5⟩\langle 5, -5\rangle⟨5,−5⟩. One original vertex is at (−1,8)(-1,8)(−1,8); this is the vertex’s image after translation.
(4,3)
Rotate the triangle with vertices: 90° clockwise about the origin.
