$\bf G(\stackrel{x_1}{-2}~,~\stackrel{y_1}{6})\qquad 
H(\stackrel{x_2}{5}~,~\stackrel{y_2}{-3})
\\\\\\
% slope = m
slope = m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-6}{5-(-2)} \implies \cfrac{-3-6}{5+2}\implies \cfrac{-9}{7}$

Write the standard equation of a circle with center (-9,-4) and radius 15.

Oksi-84 [34.3K]

Answer:

Equation of a circle:

radius = the sq. rt of (x - h)^2 + (y - k)^2

Plug in the values for the center of a circle and the radius:

15 = the sq. rt of (x + 9)^2 + (y + 4)^2

(x + 9)^2 + (y + 4)^2 = 225

The answer is A or the first one.
