Final answer:
The slope of the equation is -2 and the y-intercept is 4.
Step-by-step explanation:
The given equation is 6x + 3y = 12. To find the slope and the y-intercept of this equation, we need to rewrite it in slope-intercept form, which is in the form y = mx + b, where m is the slope and b is the y-intercept.
So, let's rearrange the equation: 3y = -6x + 12. Now, divide both sides of the equation by 3 to isolate y: y = -2x + 4.
From this form, we can see that the slope is -2 and the y-intercept is 4.
