Find the slope of the line whose equation is 15 + 3x = 2y. 3/2 -3/2 15/2

The answer is:  [A]:  "3/2" .

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].
