Which of the following equations is an example of inverse variation between variables x and y ?
2 answers:
The option C) y = 15/x
a) y = 15 x is an example of direct variation, with proportionality constant = 15
b) is an example of linear variation (it is the equation of a straight line that does not pass through the origin)
c) y = 15/x => y*x = 15 = constant which is the characteristic of an inverse relation
d) y = x/15 is an example of an inverse relation, with proportion constant = 1/15
Answer: Y=15\x

Answer:
C
Step-by-step explanation:
x+4y=-12
x+7y=-15
subtract
-3y=3
y=-1
x+4(-1)=-12
x=-12+4=-8
so point is (-8,-1)
First you have to find the measurement of the entire line,which will be equal x, than plug in in the equation between L and M
