Question

Find the distance between (8,0) and (1,0).

Answer 1

(8,0) - (1,0) = an horizontal run of 7 with no vertical rise or (7,0)

Answer 2

7 units

Explanation:

since the y- coordinates of both points are equal , both 0

then the 2 points lie on a horizontal line

then the distance between them is the absolute value of the difference of the x- coordinates , that is

distance = | 8 - 1 | = | 7 | = 7 units

or

distance = | 1 - 8 | = | - 7 | = 7 units
