find PD if the coordinate of P is -7 and the coordinate of Dis -1
The distance between two points in a one-dimension coordinate system is D=(x2-x1).
So if P(-7), D(-1),
The distance between the two points is:
D=(-7)-(-1)
=?

To find the distance between two points on a number line, you can use the formula for the distance between two points:
Distance = |(Point 2) - (Point 1)|
In this case, you want to find the distance between point P (-7) and point D (-1). Applying the formula, we have:
Distance = |-1 - (-7)|
Simplifying, we get:
Distance = |(-1) + 7|
Distance = |6|
Therefore, the distance between P (-7) and D (-1) is 6 units.
