1. Number of origins in a cartesian plane 2. x-coordinate of any point on x-axis can be _______ 3. Any of the coordinate axes is a straight ________ 4. The ordinate of the point (1,9) is ________

Answer» <html><body><p>e-dimensional space, the Cartesian coordinate system is based on three mutually perpendicular coordinate axes: the x-axis, the y-axis, and the z-axis, illustrated below. The three axes intersect at the point called the origin.______________________________________________________________Since <a href="https://interviewquestions.tuteehub.com/tag/every-976721" style="font-weight:bold;" target="_blank" title="Click to know more about EVERY">EVERY</a> point on the x - axis has no distance (zero distance) from the x - axis, <a href="https://interviewquestions.tuteehub.com/tag/therefore-706901" style="font-weight:bold;" target="_blank" title="Click to know more about THEREFORE">THEREFORE</a>, the y - coordinate of every point <a href="https://interviewquestions.tuteehub.com/tag/lying-1081801" style="font-weight:bold;" target="_blank" title="Click to know more about LYING">LYING</a> on the x - axis is always zero. Thus, the coordinates of any point on the x - axis are of the <a href="https://interviewquestions.tuteehub.com/tag/form-996208" style="font-weight:bold;" target="_blank" title="Click to know more about FORM">FORM</a> (x, 0), where x is the distance of the point from the y - axis.______________________________________________________________ The core concept is that on a 2-dimensional (Euclidean) plane, any point can be represented by a pair of real numbers, using two non-parallel straight lines. The point where these two non-parallel reference lines meet is termed the origin of the reference axis. ... Such axes are called Rectangular Axes.___________________________________________________________</p></body></html>
