Answer:
B.y increases as x increases.
Step-by-step explanation:
We are given that a graph.
We have to find the relationship between x and y.
From given graph, we can see that
The line is passing through the origin.
It means when x=0 then y=0
Direct proportional: It states that
It means when x increases then y also increases.
When x decreases then y also decreases.
Inversely proportional:It states that
When x increase then, the value of y will decreases.
When x decreases then, the values of y will increase.
We can see that from given graph, when x increases then, the values of y is also increases.
When x decreases then, the value of y also decreases.
Therefore, x is directly proportional to y.
Hence, option B is true.

Answer:
The graph with B(2,-3) i.e) y= x goes through the point M(-10,15).
Step-by-step explanation:
Consider M(-10,15) and given that equation is y = kx.
Now, substitute M(-10,15) in the equation
⇒ 15 = k × -10
⇒ k = =
⇒ y = x
Now, check with the given points B(2,-3) and B( , -2)
1) B(2,-3)
y = x
⇒(-3) = × 2
⇒ -3 = -3 ⇒ LHS = RHS
⇒ B(2,-3) is the required point.
2) for b( , -2)
LHS ≠ RHS.
So,The graph with B(2,-3) i.e) y= x goes through the point M(-10,15).
