The line that passes through the point (2,-8) and
has a slope of -1 is given by the equation y +
J(x-1

y = -x - 6

Step-by-step explanation:

I graphed the coordinate point on the graph and found an equation of the line that goes through the point with a slope of -1.

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

you,
