- When writing an equation of a line given two points, which form should you use if you do not know the y-intercept?

I don’t get can someone answer this?

Step-by-step explanation:

If you want to write the equation of a line given only 2 points, you would first find the slope of both points using the slope formula, [(y2-y1)/(x2-x1)].

Then once you have your slope, you would use the point-slope formula to write your equation. (y-y1=m(x-x1)).

c is the final : )

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
