Answer:
1st option
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y = ← k is the constant of variation
To find k use (3, 8 ) , that is x = 3 when y = 8 , then
8 = ( multiply both sides by 3 )
24 = k
y = ← equation of variation
These following ordered pairs are on the graph:
- (0,1)
- (5, 24)
- (-2,3)
-------------------------------
An ordered pair (x, f(x)) will be on the graph if replacing them into the equation, we get an equivalence.
-------------------------------
The equation is:
-------------------------------
(0,1)
Here, we test
Replacing into the equation:
False, so not on the graph.
-------------------------------
(0,1)
Here, we test
Replacing into the equation:
True, so on the graph.
-------------------------------
(3,5)
Here, we test
Replacing into the equation:
False, so not on the graph.
-------------------------------
(5,24)
Here, we test
Replacing into the equation:
True, so on the graph.
-------------------------------
(-2,3)
Here, we test
Replacing into the equation:
True, so on the graph.
-------------------------------
(-4,-17)
Here, we test
Replacing into the equation:
False, so not on the graph.
