We can use the two points we know The coordinates of to draw a slope triangle, like the one below. Start by finding the change in vertical and horizontal distance from 5,3 to 7,7. That’s the same as a vertical side length and horizontal side length of the slope triangle

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
