Question 1163765
<pre>
Any line parallel to to the line ax+by=c can have equation ax+by = K, where
K ≠ c
</pre>
What is an equation of the line which is parallel to 3x+7y = 4 and passes
through (5,-2) 
<pre>
It can have the equation 3x+7y = K where K ≠ 4

To find K, simply substitute x = 5 and y = -2 in

     3x+7y = K  
3(5)+7(-3) = K
     15-21 = K
       -16 = K

Answer:  3x+7y = -16
