(me) find each of the following based on the points being on the number line. 6. find the length of __ pd if the coordinate of p is -7 and coordinate of d is -1. 7. find the length of __ sk if the coordinate of s is 17 and the coordinate of k is -5. 8. find the coordinate of b if __ ab = 8 and the coordinate of a is -2. 9. find the coordinate of x if __ xy = 1 and the coordinate of y is 0.

length can be found using:  XY = |x - y|

6) PD = |P - D|  = |-7 - (-1)|   = |-7 + 1|   = |-6|   = 6

7) SK = |S - K|  = |17 - (-5)|   = |17 + 5|   = |22|   = 22

8) AB = |A - B|  

     8 = |-2 - B|  

8 = -2 - B         or      -8 = -2 - B

10 = -B              or       -6 = -B

-10 = B              or       6 = B

9) XY = |X - Y|  

     1  = |X - 0|  

     1  = |X|

1 = X               or         -1 = X

let's solve your equation step-by-step.

4x+2=2x+12

step 1: subtract 2x from both sides.

4x+2−2x=2x+12−2x

2x+2=12

step 2: subtract 2 from both sides.

2x+2−2=12−2

2x=10

step 3: divide both sides by 2.

2x

2

=

10

2

x=5
