Without graphing, determine the x- and y-intercepts of the graph of $g(x)=\frac{4}{5}|x-2|-2$. Then sketch the graph and label important points.

Table lists a liquid’s mass and volume data. Create a line graph of this data with the volume on the x-axis and the mass on the y-axis. Calculate the slope of the line. What information does the slope give you? Mass v. Volume.
