Hi, I asked this question yesterday and I am still struggling with it, can someone please help me, thank you!

State the image of the given point after the following transformation:

(2,7) after a vertical stretch by a factor of 1/2 about the line y=1 followed by a horizontal stretch by a factor of 3 about the line x=3.

I did see that question yesterday, but was waiting until some other math tutor might understand what you mean by "a stretch by a factor of 1/2 about the line y=1 ".

I am going to guess that you mean the distance of the point (2,7) to the line y = 1 cut in half.

After that the new point would be (2,4)

Now this new point is -1 units from x=3, so I would guess we move it 3(-1), which would place it at (-1,4)

I don't know if this is what you ask?
