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].
