C. 5/2.

You can get the scale factor by putting the measurements of similar sides on a fraction,

In this case 20/8 =5/2, 10/4 = 5/2

The another way to represent the same line, for solving $y$ will be: $y= 5-\frac{2}{3}x$

Explanation

Given equation of the line is: $2x+3y=15$

"Solving $y$ " means we need to get $y$ alone in left side. So, we will eliminate all other terms except $y$ from the left side.

First we will subtract 2x from both sides. So, we will get......

$2x+3y-2x=15-2x\\ \\ 3y=15-2x$

Now, we will divide both sides by 3 for getting $y$ alone. So.....

$\frac{3y}{3}= \frac{15-2x}{3}\\ \\ y= 5-\frac{2}{3}x$

Thus, the another way to represent the same line, for solving $y$ will be: $y= 5-\frac{2}{3}x$
