How do you plot a graph of data?
Follow these simple steps:
- First, find the value for x on the x-axis.
- Next, find the y-value – in this case, y=1100, so find 1100 on the y-axis.
- Your point should be plotted at the intersection of x=0 and y=1100.
- Finally, plot the point on your graph at the appropriate spot.
