What is the image of the point 6 2 under the following trans

What is the image of the point (6, 2) under the following transformation: projection onto the y-axis, then dilation by a factor of 8? What is the image of the point (1, 0) under the following transformation: dilation by a factor of 2, then counterclockwise rotation by 90 degrees, then projection onto the x-axis.

Solution

Ans(1):
projection of (6,2) on y-axis gives (6,0)
dilation by factor of 8 gives mean multiply by 8 so final answer is (48,0)
-----------
Ans(2):
dilation by factor of 2 gives means multiply by 2 so (1,0)changes to (2,0)
counter clockwise rotation by 90 degree gives final answer (0,2)
