Help plz! I dont understand this problem!! Use the point and the slope to graph each line. Write the equation of the line.
a) The line contains point (2,-2) and is perpendicular to a line with slope -1.
b) The line passes through point (-1,-4) and has slope -2.

i got 10.28 but that rounds up to 10.3

the answer is two. hope this !

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
