Best ResponseYou've already chosen the best response.0When you're dealing with scale factors, you're multiply the the preimage by a number to get the image. So, we get \((N'(2,1)=N(6k,3k)\) where k is the scale factor. Can you figure it out from here (aka solve for k)?

Best ResponseYou've already chosen the best response.0Ok, to make it a bit simpler, we need to solve for the value of k that would satisfy the equations \[2=6k\]AND\[1=3k\]Does that help?

Best ResponseYou've already chosen the best response.0Let's start with the first equation first. How do you solve 6k = 2?

Best ResponseYou've already chosen the best response.0Well, you're trying to get k by itself. k is multiplied by 6, to get rid of it, you divide by 6. on both sides.\[\frac{6k}{6}=\frac26\]\[k=???\]

Best ResponseYou've already chosen the best response.0Yup! k=1/3. You want to make sure that you got the number right, so plug it back in to see if it is correct. When you do plug it in, you see that k works for both equations, and you found the scale factor. :)

Best ResponseYou've already chosen the best response.3we have pre image point =(6, 3) and we hav new point = (2,1) scale factor is the number multiplied with the pre image point (6,3) to get the new point (2,1) lets take the scale factor as m so (6m,3m)=(2,1) so 6m=2 frm here we get m=1/3 and also 3m=1 frm here we get m=1/3 so scale factor is 1/3
