welshfella · Answer

you need to use the distance formula

D  =  sqrt [ (y2-y1)^2 + (x2 -x1)^2]


where the 2 points are (x1,y1) and (x2,y2)


here you can take y1 = 10 and y2 = 10,  x1 =  30 and x2 = 15.

Points ( 30, 10 ) and ( 15, 10 ) are the end points of a line parallel to the x axis and 30-15 or 15 units in length.
