Which ones are 2 units apart

D and G

Step-by-step explanation:

D and G are 2 units apart

Your first answer was C and that was in fact (10,5)All the other units are different from each other thusD and G are correct because D going up two units is GD is equal to {7,-8}G is equal to {8,-6}From D you go up 2 and right 1

Star and K

These two are also two units apart to be sure to look at the question carefully for they are two units to the right thusStar is equal to {-7,-8}K is equal to {-5,-7}From Star, you have to go right 2 then go up 1

I’d say letter a..
