<h2>(9, -2) and (0, 4)</h2>
Step-by-step explanation:
![2x+3y=12\\\\(9,\ y)\to\text{put x = 9 to the equation of a line:}\\\\2(9)+3y=12\\18+3y=12\qquad\text{subtract 18 from both sides}\\3y=-6\qquad\text{divide both sides by 3}\\y=-2\\\boxed{(9,\ -2)}\\\\(x,\ 4)\to\text{put y = 4 to the equation of a line:}\\\\2x+3(4)=12\\2x+12=12\qquad\text{subtract 12 from both sides}\\2x=0\qquad\text{divide both sides by 2}\\x=0\\\boxed{(0,\ 4)}](https://tex.z-dn.net/?f=2x%2B3y%3D12%5C%5C%5C%5C%289%2C%5C%20y%29%5Cto%5Ctext%7Bput%20x%20%3D%209%20to%20the%20equation%20of%20a%20line%3A%7D%5C%5C%5C%5C2%289%29%2B3y%3D12%5C%5C18%2B3y%3D12%5Cqquad%5Ctext%7Bsubtract%2018%20from%20both%20sides%7D%5C%5C3y%3D-6%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%203%7D%5C%5Cy%3D-2%5C%5C%5Cboxed%7B%289%2C%5C%20-2%29%7D%5C%5C%5C%5C%28x%2C%5C%204%29%5Cto%5Ctext%7Bput%20y%20%3D%204%20to%20the%20equation%20of%20a%20line%3A%7D%5C%5C%5C%5C2x%2B3%284%29%3D12%5C%5C2x%2B12%3D12%5Cqquad%5Ctext%7Bsubtract%2012%20from%20both%20sides%7D%5C%5C2x%3D0%5Cqquad%5Ctext%7Bdivide%20both%20sides%20by%202%7D%5C%5Cx%3D0%5C%5C%5Cboxed%7B%280%2C%5C%204%29%7D)

That would be at quadrant to so you want to plot -1 and then half a box to the left. Then you want to point -5 and then just go up half. Hope this helps
Answer: 3 1/2
Step-by-step explanation: First you have to convert the fractions so that they all have the same denominator. Using 12 will be the easiest. 1 and 1/3 equals 16/12 because 1/3 equals 4/12 and 1 equals 12/12. 3/4 equals 9/12. 2/3 equals 8/12. And 3/4 equals 9/12 again. 16/12 plus 9/12 plus 8/12 plus 9/12 equals 42/12. 42/12 in the simplest form would be 3 and 1/2, because 42 divided by 12 is 3.5.
