What is the correct equation?

Answer:
B
Step-by-step explanation:
The graph passes through (0,0) so this point HAS to satisfy the equation.
Let's check this. We put 0 into both x and y and check if the equation holds true:
A) y = -2 NO!
B) y = 0 YES!
C) 1 = 18 NO!
D) y = -2 NO!
Definitely the equation of this graph is B.
Note: If there were more than one "yes" in our checking, then we would have taken another point and boiled it further down. But we didn't need to.
Answer:
Choice B is equation for this graph.
Step-by-step explanation:
We have given the graph.
We have to find the correct option for this graph.
As this line passes through (0,0) so,check all equations by putting x = 0 we get,
Choice A : y = -2 (it is not true)
Choice B : y = 0 (it is true)
Choice C : 1 = 18 (it is not true)
Choice D: y = -2 (it is not true)
So, choice B is equation for this graph.
