Key idea

Same y → horizontal side → subtract the x-values. Same x → vertical side → subtract the y-values. Length is never negative. When the side crosses zero, the two distances ADD: from −5 to 4 is 5 + 4 = 9 units.

Sample problems

Find the length from (1, 4) to (8, 4).
Find the length from (3, 2) to (3, 10).
Find the length from (−6, 5) to (−1, 5).
Find the length from (−2, −7) to (−2, −1).

Common mistakes to watch for

Subtracted the y-values and got 0. Matching coordinates tell you which pair to leave alone.
Subtracted the x-values and got 0.
Answered 1 by computing 3 − 4, ignoring the negative sign. When a side crosses zero the two distances ADD.

The answer key explains each one, so you can tell what a wrong answer means.
