Find the equation of a line given the point and slope below. arrange your answer in the form y = mx + b, where b is the constant.
(1, 3)
m = 3
i need with this question and others like it, an explanation would be great, im on a deadline and need to finish these as soon as possible ty

For this case we have that by definition, the equation of a line in the slope-intersection form is given by:

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the data we have to:

So, the equation is of the form:

We substitute the point and find b:

Finally, the equation is of the form:

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
