Which of the following is the correct point-slope equation for the line that passes through the point (-6, -1) and is parallel to the line given by y = 7x + 31?
A. y + 1 = 7(x+6)
B. y-1 = 7(x-6)
C. y + 6 = 7(x+1)
D. y-1 = -7(x-6)

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

step-by-step explanation:

i got 86 for this

hope this !

if you need an explanation just ask

lol.

it's ok we all do this sometimes.

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.

you,
