You go 4 along the x - axis and 1 up along the y- axis
For the second one, you go -1 along the x-axis and -3 up along the y- axis
In other words (x,y) in a coordinate for a graph
Hope that helped :) Don't worry I am rubbish at that as well... but I always remember (x,y) :)
answer my question please as well <3 xx
