Answer:
perpendicular slope = - 
Step-by-step explanation:
given a line with slope m then the slope of a line perpendicular to it is
= - 
the given slope m = 4, hence
= -

Answer:
s = 1,811 square foot
Step-by-step explanation:
Here, we want to calculate the area of the roof.
The best way to proceed here is by substitution.
We simply substitute the length and the price into the bid price equation to get the area of the roof.
From the original equation, the formula to use is ;
P = 1.85s + 4.2f
now from what we are given; s = ?
f = 190 feet and P = $4148
substituting these values, we have;
4148 = 1.85s + 4.2(190)
4148 = 1.85s + 798
1.85s = 4148 -798
1.85s = 3350
s = 3350/1.85
s = 1,810.810810810811
To the nearest square foot, s = 1,811
