Answer: See below
Step-by-step explanation:
Temperature
The temperature is always either over 0 or below zero. An example would be at night it could be -2 degrees and half way through the day it might be +23 degrees.
Altitude
Above sea level is positive, below sea level is negative
Money (Loans)
Savings are positive, loans are negative.
So parallel lines have the same slope, but perpendicular lines have negative reciprocal slopes. So a slope of 3/2 will have a negative reciprocal of -2/3.
-x + 2y = 4
2y = x + 4
2y/2 = (x + 4)/2
y = 1/2 x + 2
m = 1/2, so reciprocal is -2/1 = -2
point (-2, 1)
point-slope form:
y-y1 = m (x-x1)
y-1 = -2 (x- -2)
y-1 = -2 (x+2)
y-1 = -2x -4
y = -2x - 3, or:
2x + y = -3
