find the slope and y-intercept of the graph of the equation. explain each step and how you got it.

12x + 4y= 24

-first you move the 12x to the other side of the equation to isolate the 4y
-Divide the whole equation by 4 to give a single y
-this gives you y=-3x+6
-the slope is -3 because your "m" term is the slops in a standard equation(which you have)
-the y-intercept is found by setting y to 0. you would solve: 0=-3x+6 which gives you 2. (isolate the -3x; divide by -3 to give a single unit)
That's it!
