Write the equation of the line with a slope of 4 that contains the point (8,5)

y = 4x -27

Step-by-step explanation:

We can use the point slope form of the equation for a line

y-y1 = m(x-x1)

where m is the slope and (x1,y1) is the point

y-5 = 4(x-8)

Distribute

y-5 = 4x - 32

Add 5 to each side

y-5+5 = 4x -32+5

y = 4x -27

This is in slope intercept 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
