y = mx + b is standard form where m = slope and b = y intercept
6x - 2y = 18
-2y = -6x + 18
-y = -3x + 9
y = 3x -9
m = slope = +3

When graphed, or written in the form [ y = f(x) ], the slope is -3 .
Get in form first.6X - 2Y = 18- 2Y = - 6X + 18Y = 3X - 9====================zero out Y to find X intercept3X - 9 = 03X = 9X = 3==========X intercept
If you mean: 3x-2y = -2 and 6x-4y = 0 then they are parallel lines having the same slope or gradient of 1.5
6x = 10-y y = -6x+10 The slope is -6 and the y intercept is 10
