Let ax+by=c be the given(known) line
slope of this line (m₁) = -a/b
Let m₂ be the slope of required line
Since given line and required line are perpendicular to each other, the product of their slopes must be equal to -1
Therefore, m₁.m₂ = -1
(-a/b)m₂ = -1
m₂ = b/a
Therefore, by slope-intercept form, line perpendicular to given line can be given by,
y=m₂x+c
y=(b/a)x+c
Therefore, ay-bx=c
or bx-ay+c = 0
Where c is constant and it can be determined according to the conditions given in questions.
Therefore the required line is,
bx-ay+c=0
10in would be the appropriate scale factor for the drawing. 2000 is 10x200. If each inch represents 200 feet, then you would need 10 to reach the desired scale factor of the original building

Answer:
5/7
Step-by-step explanation
When dividing a fraction by a fraction it is the same as multiply the inverse of the bottom fraction, so 5/9 times 9/7 so the 9's cancel and your left with 5/7

f-12=2(b-12)
f=2+b
2+b-12=2(b-12)
b-10=2b-24
minus b both sides
-10=b-24
add24
14=b
14-12=2
2+2=4
