47 - 5*3 - 2*1 = 30. 30/3 = 3, so add three plus five plus two = 10 kids
A rigid transformation is
defined to be one in which the pre-image of the object and its new image after
the transformation both have the exact same size and shape. So the answer
in this question is:
<span>D. a circle's shape is preserved regardless of any rigid
transformation</span>

Y = mx + b
m is your slope AKA rate of change
b is the y intercept.
from the graph we can see that the y intercept (b) is 15. (look at the y axis and see what point the line crosses on the y, here it is 15, in-between 10 and 20)
slope is rate of change. to figure this out remember slope = rise over run:

so pick two points. how much does one point rise after the other point you picked? In the graph it rises 1 square so rise = 1
Now looking at the same two points, how far away from each other are they on the x axis? Looking at the graph they are 2 squares away from each other. so run = 2
Now plug these numbers into the rise over run formula:

Now we have everything we need to put into our formula for a line:


For number 16 you should get:
