Answer 2

Count the number of units to go from (-3, 1) to (1, 1). This is fairly simple to do because the y-coordinate is the same, but the x-coordinate is different. But to find the units in between the points, you would just need to subtract the x-coordinates: 1 - (-3)

Answer 3

i will be + right

Answer 4

If you mean to say that the unit count will be positive, then yes.
