I need to construct a line graph showing bacterial growth.
It gives me a table with the hours, and then beside it, the number of bacteria at each hour.
How can I make this a line graph?
Which variable goes on which axis?
Thanks

Take the time as the x axis(horizontal) and number of bacteria as y axis(vertical). Take the unit of x axis as hours/minuter, which ever's comfortable for drawing. In the y axis take the number in the multiples of 10 or 100 or 1000 or any other power of 10, that suits the data best. Draw the graph from the first data. Dot the point which's the meeting point of the vertical line(imaginary line you take to draw. Don't draw this line)from time and the horizontal line(again this's also imaginary line)from the corresponding number of bacteria.

You can plot time on the x-axis (as time would increase constantly, hour by hour) and plot the number of bacteria on the y-axis.
If the relationship between time and number of bacteria is not directly proportional to each other, then you may have to draw a 'line of best fit' after plotting all your points. However, if the relationship is directly proportional then you'll come with a linear graph straight away.
You can even come up with an equation for this line that would further describe the mathematical relationship of bacterial growth.
Hope this helps.

Time on the X axis and number of bacteria on the Y.
