Find the equation of a line that is perpendicular to the line y=1/8x+4 and contains the point (-8,0)
In-s [12.5K]

answer

y = -8x - 64

finding slope

a perpendicular line has a slope that is the negative reciprocal of the original graph

since the slope of y = \frac{1}{8} x+4 is \frac{1}{8}, the perpendicular line has a slope of \frac{-8}{1} =-8

values

the equation of a line is y = mx + b

with the point (-8, 0), x = -8 and y = 0

we found the slope to be m = -8

plug in values

y = mx + b

0 = -8(-8) + b

0 = 64 + b

b = -64

final equation

plug m and b into y = mx + b to get

y = -8x - 64

Which statement best defines a universal law
goldenfox [79]
Answer: B. It is in effect at all times.

Explanation:
By definition, a universal law is immutable, meaning that it does not change and it is in effect at all times. 

This definition should be appled within the scope of what "universal" means.
For example, the law of "Cause and Effect" is stated in physics by Newton's third law: To every action, there is an equal and opposite reaction.  

Discussion:
Our perception of the universe is limited usually to our solar system, within a physical and material universe. We cannot be certain that our accepted universal laws apply in the same manner in a nonmaterial or spiritual universe.
