Answer:
(x +1)^2 +(y -3)^2 = 4
Step-by-step explanation:
The equation of a circle centered at (h, k) with radius r is ...
(x -h)^2 +(y -k)^2 = r^2
The graphed circle is centered at (h, k) = (-1, 3), and has radius 2, so its equation is ...
(x +1)^2 +(y -3)^2 = 4
Those ratios are not equivalent because 240 divided by 16 is 15 and 560 divided by 28 is 20.
Answer:
The slope is 
Step-by-step explanation:
Take the general equation of a straight line 
Here
is the slope of the line.
So let's get the equation of the line in the question in the same form.

Add
to both sides: 
Add
to both sides: 
Divide by
to get it into the general equation: 
Now compare it to the general equation to find the value of
. The value of
is the coefficient of
which we can see is 
I believe it is A and Yes
The bigger the price is on an item, the more tax you would have to pay, so both numbers increase. As for whether or not there is a line through the dots, you use a line when you could go inbetween the points. For example, with this question you can have 0.24, 0.86, or any other number as the price and it would make sense. If the question was sales tax on a certain number of shirts, well, you can't buy half a shirt so you don't need anywhere inbetween the dots.
Proportional in these kinds of problems means whether or not the line curves. If it doesn't and is a straight line, then it is proportional.
