Find PD if coordinate of P is -7 and the coordinate of D is -1

PD = 6 units

Step-by-step explanation:

Co-ordinate of P = - 7

Co-ordinate of D = - 1

So length of PD = | - 7 | - | - 1 |

= 7 - 1

= 6 units

( Length can't be negative at all )

step-by-step explanation:

first, eliminate the parenthesis:
