Graphing problem, if mass is on the x axis and volume on the y axis. Using the gradient, how do i find the density of the object?
I'm not allowed to caculate it as density = mass / volume

If you plot a graph of y (volume) against x (mass) then the density can be found from the gradient of the graph. This will yield the volume per mass of the object. To find the density take the inverse of the gradient. If we let m be the gradient from the graph, then
Density= 1/m.

You require Mass / Volume.
For gradient you will be taking the y-axis value over the x-axis value, therefore you need mass on the y-axis and volume on the x-axis.
then y / x will give you a value for density.

To find the gradient, you need 2 coordinates on the graph. it would be advisable if you pick easily-read points like an exact (2,1). Once you picked 2 coordinates, name them (x1, y1) and the other (x2, y2) then use the formula, y2-y1 / x2-x1 to find the gradient, and that would be the answer! =)
