Proportional relationships are also known as direct variation, in which you multiply by a constant, it is represented by the equation y = kx.
Therefore, this is not Proportional because we are ADDING $20 more and not multiplying by a constant.
We have an equation: ?/18 = 2/3
Cross multiply:
3*? = 2*18
⇒ ?= 2*18/3= 12.

Answer:
This graph is NOT a function.
Step-by-step explanation:
A graph is a function only if there is exactly one y-value for every x-value. In this case, there are many x-values that have two y-values, making this graph not a function.
Let me know if this helps!
