rdinates. Distances measured parallel to OX are called a?, withor without a suffix, {e.g.Xj, x.-^... x\ x,...), and distancesmeasured parallel to OY are called y, with or without asuffix, (e.g. 2/i, 2/2,--- 2/. y,---)- If the distances OM and MP be respectively x and ?/,the coordinates of P are,… … COORDINATES. 9 then from 21 measure a distance MP {=y) parallel to OYand we arrive at the position of the point P. For examplein the figure, if OM be equal to the unit of length andMP= WM, then P is the point (1, 2). 16. Produce XO backwards to form the line OX andYO backwards to become OY. In…
