Which equation represents a proportional relationship between the x and y values?

y = kx

Step-by-step explanation:

We have to write an equation that states that the relationship between x and y is proportional.

Since x and y are proportional, so we can write symbolically  

y ∝ x

⇒ y = kx {Where k is the constant of proportionality}

So, this is the required equation. (Answer)

Geometrically it signifies that it is a straight line having constant slope k and it passes through the origin.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
