Perpendicular lines have slopes that are opposite signs and reciprocals.
Example: If one line has a slope of 5/3, then the perpendicular slope is -3/5.
In your case, your first line has a slope of -1/5. The perpendicular slope will be positive and will be 5/1.
The slope of a line perpendicular to the given one is 5.

Step-by-step explanation:
Answer:b 27 feet
Step-by-step explanation:You need a ladder that will reach up a 25 foot tall house when placed 10 feet away from the house.
1 lb / 0.45 = 2.22
so approximately 2.22 kilograms per pound
divide price per pound by kilometers per pound
1.44 / 2.22 = 0.648
round to 0.65, so it costs $0.65 per kilogram
