The answer is: [A]: "3/2" .
_______________________________________
Step-by-step explanation:
_______________________________________

Given: 15 + 3x = 2y ; rewrite this equation in: "slope-intercept form" ;

which is: "y = mx + b " ; m = the slope.

____________________________________
Given: 15 + 3x = 2y ; ↔ 2y = 3x + 15 ;

Divide each side of the equation by "2" ; to isolate "y" on the left-hand-side of the equation;

2y / 2 = (3x + 15) / 2 ;

to get:

y = (3/2) x + (15/2) ;

The equation is in "slope-intercept form" ; " y = mx + b" .

The slope, "m" is: "(3/2)" ; which is: Answer choice: [A].
