The answer would be A. m= -3/5 and b=-4/5
"m= -5-1 divided by 7--3
or, -6/10
or, -3/5.
to find the (B)
<span><span>(-3,1). y=mx+b or 1=-3/5 × -3+b, or solving for b: b=1-(-3/5)(-3). b=-4/5.</span><span>(7,-5). y=mx+b or -5=-3/5 × 7+b, or solving for b: b=-5-(-3/5)(7). b=-4/5.</span></span>See! In both cases we got the same value for b. And this completes our problem.

Answer:
0.08641975308
Step-by-step explanation:
3 INCHES= 42 MILES. 42 <span>MILES</span> DIVIDED BY 322 MILES= 7.6
3X7.6= 22.8 INCHES APART
<span>A = pi r^2
dA/dt = 2 pi r dr/dt
dr/dt = 15 cm/s
a) r = 30
dA/dt = 2 pi (30) (15) = 900 pi cm^2/s
b)
A = 9 = pi r^2
r = 3 / sqrt(pi)
dA/dt = 2 pi( 3/sqrt(pi)) (15) = 90 sqrt(pi) cm^2/s</span><span>
