Determine the set of all points in the plane that are equidistant
from the direction 3x + 5y −1 = 0 and from the direction 3x + 5y + 10 = 0.

3x5y I think I'm not sure

Step-by-step explanation:

3x=5y

hello from mrbilldoesmath!

answer:

a(n) - a(n-1) -3

discussion:

this ones a bit interesting. given a(n) = 5 - 3n consider this:

a(n-1) = 5 - 3(n-1)

          = (5 - 3n) + 3             => but a(n) = 5 - 3n, the first term

          = a(n)   + 3                 => subtract 3 from both sides

a(n-1) -3 = a(n)  

or

a(n) - a(n-1) -3
