Slope intercept is y=mx+b.
Isolate y to get it from standard form to slope intercept form.

3y=-2x+1470
y= -2/3x+ 490

Slop intercept form is y+mx+b. With this in mind, you would simply solve the equation for y and reorganize the the other side.

 2x+3y=1470
       /3       /3
 2x+y=490
-2x      -2x
 y=-2x+490
