The scale factor is what you multiply to get the new shape, so if it was (x+1,Y+1) the entire shape would enlarge by 1 .Hope this helps :)
You have two buttons of different lengths.
First with length 
in and second with length 
in. The first one is larger, then the difference in length between them is:
Answer: 
in.
Answer:
h(-2) = 13
h(5) = -1
Step-by-step explanation:
Given the function
h(x) = -2x + 9
Evaluating at x = -22
substitute x = -2
h(-2) = -2(-2) + 9
h(-2) = 4 + 9
h(-2) = 13
Therefore,
Evaluating at x = 5
Given the function
h(x) = -2x + 9
substitute x = 5
h(5) = -2(5) + 9
h(5) = -10 + 9
h(5) = -1
Therefore,
so notice above, the circle is centered at h,k or 0,0, the origin, and has a ratio of 5.
and y = 2, is just a horizontal line, check the picture below.
