Y - 3 = 0
y = 3
learn this : (it really does help)
HOY -- horizontal line, 0 slope, represented by y = a number.
VUX -- vertical line, undefined slope, represented by x = a number.
so if u have y = 3....this is a horizontal line with a 0 slope <==
** if it would have been x = 3, then u would have had a vertical line with an undefined slope
Since f(x) is constant with respect to x, the derivative of f(x) with respect to x is 0.0

It would take 36 minutes. If you use unit rate, you would take 20min/5people and see how many minutes does it take to paint one wall. Which would be represented by 4min/1person. To find how many minutes it would take for 9 walls, you get 4min/1person to become 9 people for the denominator. Then, whatever you do to the denominator you do to the numerator. So, 4 times 9 is 36. Therefore, making the answer 36minutes/9people.
