Answer:
y =
x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 2x + 2 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= 
The line crosses the y- axis at (0, 1) ⇒ c = 1 , then
y =
x + 1 ← equation of perpendicular line
We must assume that all workmen work at the same rate, and keep it up forever.
More men ==> fewer days
so the proportion is: 30/25 = x/10
Cross-multiply the proportion:
300 = 25 x
Divide each side by 25 :
x = 300/25 = <u>12 men</u>
