The graph of a relation of the form y = 5 is a line parallel to the x-axis because the y value never changes. A line parallel to the x-axis is called a horizontal line. The graph of a relation of the form x = 5 is a line parallel to the y-axis because the x value never changes. A line parallel to the y-axis is called a vertical line. Plot the graph of each of the following relations: horizontal line, vertical line.
Horizontal axis of theECG graph paper represents time in milliseconds (ms) while the vertical axis represents amplitude or voltage in millivolts (mV). Each1-mm-division on the horizontal axis is 40 ms; each 5-mm-division is 200 ms. Two 5-mm-divisions on the vertical axis are calibrated to represent 1 mV. Despite the latter, ECG waves are commonly described by their height in mm rather than by their strength in mV.
