Which description best describes the solution to the following system of equations y = 2x + 3
y = -x + 6
lines y = -2x + 3 and y = -x + 6 intersect and the x axis
lines y = 2x + 3 and y = -x + 6 intersect at the y axis
line y = 2x + 3 intersects the line y = -x + 6
line y = 2x + 3 intersects at the origin

The third choice, which would be:

Line intersects the line .

Step-by-step explanation:

On a graph, line and line  do intersect each other, but not in the x-axis, y-axis, or at the origin.

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
