As y is directly proportional to x, there must be a constant n, where y=nx
n=y/x
n=10/15=2/3
y=(2/3)x

Answer:
The answer is D. y-10=2(x-1)
Step-by-step explanation:
First, find the slope from the two points:
m=(10-2)/(1+3)=2
let
thus, y-10=2(x-1)
Option D is a linear equation, so it represents a direct linear variation.
