Question

how to find out the initial value of the relation?

Answer 1

If you're given an equation of a line to represent something in the first quadrant, you're probably looking for that y intercept. To find the y-intercept, let x be zero in the equation of the line you're looking at. 

 

Like if you have something like 

 

y = 3x + 2

 

to find the y intercept, let x be zero then we get that when x is zero

 

y = 3(0) + 2 = 0 + 2 = 2

It's hard to tell what you need though based on the question.

Answer 2

A linear relation is in the form of y = kx.

 

x = 0 give the initial value, 0.
