Question 250743
First parallel lines have the same slope..so you know that 

y = 3x + 5 has a slope of 3

then you have the point (5, 4)

so: the new equation would start as 

4 = 3(5) + b...now solve for b

4 = 15 + b  subtract 15 from both sides
-11 = b

so now we can write the equation

y = 3x - 11

Hope this helps
