The slope of the line below is -3. which or the following is the point slope form of the line? (2,-6)

B. is your answer.

Step-by-step explanation:

Why B is your answer is based off the points and the slope. So without having the numbers in the formula, the formula is y-y_1=m(x-x_1).

-3 is m.

2 is x_1.

-6 is y_1.

You then have to put it into the formula so it is y+6 (because of the -6 and -y_1 it will equal a positive.)

So y+6=-3(x-2).

B is your answer.

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

y -5 = (-1/4)(x + 8)
