(a) <span>For the circle with equation (x – 2)^2 + (y + 3)^2 = 9, answer each question:
You have to recognize this circular equation form.
(x-h)^2 + (y-k)^2 = r^2 
where (h,k) is the center and r is the radius
------------------------------------------------ 
What are the coordinates of the center?
Ans: (2,-3)

(B) </span>The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle<span>.

(C) </span><span>Realize that the circle is centered at the origin (no h and v) and place this point there.Calculate the radius by solving for r. Set r-squared = 16. ...Plot the radius points on the coordinate plane. ...Connect the dots to graph the circle using a smooth, round curve.</span>

Column A
Viefleur [7K]
The slope m of a line passing through points P(a, b) and Q(c, d) is found using the formula:

                     m= \frac{b-d}{a-c}.

Thus, the slope in A is m= \frac{12-2}{-4-(-10)}=\frac{10}{6}=\frac{5}{3}.

The slope in B is m= \frac{-4-10}{6-18}=\frac{-14}{-12}=\frac{7}{6}.

Now, to compare 7/6  to 5/3, we can write the second fraction as 10/6.


So, the slope in A is larger than the slope in B.
