Answer:
y = -4x + 4
Step-by-step explanation:
8x+2y+2=0
turn that into slope intercept form:
y = -4x - 1
a parallel line has the same slope, but different y-intercept
y = -4x + b
put (2,-4) into the equation
-4 = -4(2) + b
you get b=4
final product:
y = -4x + 4
Let 
. Then
lies in the second quadrant, so
So we have
and the fourth roots of are
where 
. In particular, they are
<span> the equation of this circle is (x - 3)² + (y + 1)² = 4²</span>
About 390 km because you drive 130 km per hour so 130 times 3 is 390
