Answer:
solve 3x+7y=3 (rearrange to y=mx+c)
7y = -3x+3
[tex]y=\frac{-3}{7} x+\frac{3}{7}[/tex]
parallel line to this...it goes through (-6,7)
so y=(-3/7)x+c - same slope, since it's parallel
when x is -6, y is 7 (-6,7)
so...
7=(-3/7)*-6+c
7= 2.571428571428571428571428571428...+c
c= 4.428571429
then we get the equation...
[tex]y=\frac{-3}{7} x+4.428571429 (approximately 4.43)[/tex]
