Question

You are given 8 different masses and volumes for metals A-B-C. These are values that will provide the (x,y) points on your graph to show that density remains constant for each metal. Mass is plotted on the (x-axis). The slope of each line, y/x which will be mass/volume will indicate the different densities for metals A,B, and C.

Answer 2

Are you required to find the densities of these metals?
What you need to do is
1. plot on a graph, possibly all on the same graph.
(use paper, or try desmos.com graphing tool)
2. Identify the points belonging to the same metal, draw a straight through points from the same metal, with the same number of points on each side of the line, but the line must pass through the origin (0,0).
3. Calculate the slope of each line, which represents the density of the corresponding metal.
Slope, m, is calculated by
m=\(\frac{y_2-y_1}{x_2-x_1}\)
Use the following link if necessary to help you find the slope.
