WebAdd 2y to both sides to get 6x = 12 + 2y. Subtract 12 from both sides of the equation to get 6x - 12 = 2y. You want to get y by itself on one side of the equation, so you need to divide both sides by 2 to get y = 3x - 6. This is slope intercept form, y = 3x - 6. Slope is the coefficient of x so in this case slope = 3.
