Answer:
 -a/b
Step-by-step explanation:
ax+by=c
First get the equation in slope intercept form ( y= mx+b  where m is the slope and b is the y intercept)
Subtract ax from each side
ax+by -ax=-ax +c
by = -ax+c
Divide each side by b
by/b = -ax/b + c/b
y = -a/b * x + c/b
The slope is -a/b and the y intercept is c/b
We want the line parallel so it has the same slope, -a/b

Answer:
A. The length of the third side is approximately 5 feet.
B. A =  , B =
, B =  and C =
 and C =  .
.
Step-by-step explanation:
Let the triangle be ABC. Given two sides and an included angle, let us apply the cosine rule to determine the third length.
A. Let side a = 6 feet and c = 3 feet, thus;
 =
 =  +
 +  - 2ac Cos B
 - 2ac Cos B
   =  +
 +  - 2(6 x 3) Cos
 - 2(6 x 3) Cos 
   = 36 + 9 - 36 x 0.5
   = 45 - 18
 = 27
 = 27
b = 
   = 5.1962
b  = 5.2 feet
b ≅ 5 feet
The length of the third side is approximately 5 feet.
B. Given that B =  , then let us apply the Sine rule to determined the measure of A.
, then let us apply the Sine rule to determined the measure of A.
 =
 =  
 
So that,
 =
 = 
Sin A = 
Sin A = 0.99923
A =  0.99923
 0.99923
   = 87.75
A ≅ 
Since the sum of angle in a triangle =  .
.
Then, 
A + B + C = 
 +
 +  + C =
 + C = 
 + C =
 + C = 
C =  -
 - 
      = 
C = 
Thus,
A =  , B =
, B =  and C =
 and C =  .
.
