Question

What is the distance from the point (1,-10) to the horizontal axis?

The distance is ___ units

Answer 1

10

take the absolute value of the y coordinate = --10 = +10

the distance from (1,-10) to the x axis is the distance from (1,-10) to (1,0)

use the distance formula d^2 = (1-1)^2 + (-10-0)^2 = 0^2 + 10^2 = 100

d = sqr100 = 10

d =10
