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
1. 40/60 + 15/60 + 24/60 + 10/60 = 1.48
2.30/60 + 20/60 + 15/60 + 12/60 + 10/60 = 1.45
3 3/4 divide 2 1/12 = 1.8
