Question

# Find the perpendicular distance of the following points from X-axis: A) (-3,-2) B) (2,0) C) (1,8)

Solution

## A pair of Cartesian coordinates (a,b) identifies the position of a point. That point is defined as being on the line x=a where it crosses the line y=b. So by definition, that point is |b| from the X axis, and |a| from the y axis THEN A)2 unit B)0 unit C)8 unit
