Mass g. Vol.ml

#1 0.55 0.60

#2 1.75 1.80

#3 3.50 3.40

#4 5.60 5.25

#5 7.50 7.00

I need to find the slope and graph the info.

So do I make the graph with Y (Vert.) axis being Mass and Vol=x axis and plot points???

Then to Find the slope I am stuck

.60-0.55=

1.80-1.75=

3.40-3.50=

The only answer choices for slope are

1.094, 0.914 and 1.024 but I can't even get one of those choices.

Please Help Thank you!

**DrBob222**, Tuesday, October 11, 2011 at 8:36pmI think you want to plot values for mass on the y axis and values for volume on the x axis. That way the slope is y/x (mass/volume) which is density.

Draw the best straight line you can through or near the points, then choose a convenient delta Y/delta X and calculate slope.
