the first coordinate of X would be -1 + (1/3 of 5 – (-1)) which is equivalent to -1 + (1/3 of 6) which is equal to -1 + 2 which is equal to 1. This is because the -1 is the first coordinate of J.
The second coordinate of X would be 4 – (1/3 of 4 – (-3)) which is equivalent to 4 – (1/3 of 7) which is equivalent to 4 – (7/3) = 12/3 – 7/3 = 5/3.
Therefore, the coordinate of X would be (1, 5/3) or (1, 1 2/3)
4x=5 is the answer to the question
