Question

Reflect point V(-3, 4) across the line y = x, and then dilate it by a scale factor of 4 around the point (2, 1). What are the coordinates of the image?

Answer 1

Answer:

V''(10, - 15)

Step-by-step explanation:

Step 1. Draw the line y = x ;

Step 2. Put V(- 3, 4) on the coordinate plane ;

Step 3. Draw the perpendicular segment from V to the line y = x, then produce the perpendicular to the point V'(4, - 3), that distance between points and a line y = x be the same.

Step 4. Plot the point C(2, 1) and connect it with V', then produce the line to the point V'' so that CV'' = 4CV' and coordinate V'' (10, - 15)
