First you wanna see how many times 6 goes into 41 which is goes into 6 time so you would write 6 above the 1, then you would subtract 41-36 then it leaves you with 5 so you put it under the subtraction problem then add a zero to it and see how many times 6 goes into fifty which is 8 times so write 48 under the subtraction problem and it would be 2 so you add a zero now put a decimal after the 69. Like so then put 6 and put the infinite bar over the 6 tenths only and there you have it should be 69.6
You need to add 8 and -3 together to get 5 and divide 5 by 2 to get 2.5 That is the x coordinate You then need to add 2 and -4 together to get -2 and divide by 2 to get -1 This is the y coordinate (2.5,-1)
