Please Please Please Can Someone Help Me With This Problem?   Which lines if any are parallel? 1. (y = 4x + 3) 2. (y = 5/3x - 3) 3. (-5x + 3y = 2) 4. (y = -2/3x - 25)?

see first you represent these lines in the slope-intercept form y=mx+c where m is the slope and c is the y-intercept
and then parallel lines will have same slopes [i.e same value of m]

1) y = 4x + 3) 
2. (y = 5/3x - 3)
 3. (-5x + 3y = 2)  or y=5/3 x +2
 4. (y = -2/3x - 25)? 
thus 2 and 3 lines are parallel as each have their slope 5/3
