BONUS: Graph triangle ABC with vertices A(7, -2), B(8, -5), C(3, -8) and its image after the following transformations. Give the coordinates of the final image. (a) Translation: (x, y) ? (x - 9, y + 10) (b) Rotation: 270° counterclockwise about the origin (c) Reflection: in the line y = -x A'(___, ___) B'(___, ___) C'(___, ___)

Step 1
To do this, subtract 9 from the x-coordinate and add 10 to the y-coordinate of each vertex. - For vertex A(7, -2), the new coordinates after translation are (7-9, -2+10) = (-2, 8). - For vertex B(8, 5), the new coordinates after translation are (8-9, 5+10) = (-1, Show more…

Triangle ABC has coordinates A(2,0), B(-1,5), and C(4,3). Determine the coordinates of the vertices of the image after transformation: rotation 180° about the origin.

The point P(a, b) in the xy-plane is first rotated counterclockwise by 90° around the point (1, 5) and then reflected about the line y = -x. The image of P after these two transformations is at (-6, 3). What is b - a? (A) 1 (B) 3 (C) 5 (D) 7 (E) 9

The vertices of $\Delta \mathrm{ABC}$ are $\mathrm{A}(2, \square 1), \mathrm{B}(0,4)$ and $\mathrm{C}(\square 3,5)$ . Find the coordinates of the vertices of the image after the translation. (Section 4.1) $$\left(\mathrm{x}_{\mathrm{e}} \mathrm{y}\right) \rightarrow(\mathrm{x}-3, \mathrm{y}+1)$$
