15.Calculate the slope of the line for your pressure vs. quantity graph (Excel will do this for you when you determine the line of best fit, please see the tutorial available on D2L or by your own online search). What properties does this number represent

Domain eukarya; kingdom plantae should be the answer.

You need to be more specific.  i really don't know what a "motion map" is.you can draw a graph of an object's position, distance, displacement, speed,velocity, or acceleration versus time, or you can draw a graph of the object's x-position versus its y-position and not give any information about time at all.if the graph presents position or displacement against time,  then constant velocity is a straight line . . i.e. a line that has  constant slope.if the graph shows speed against time, then constant velocityis a horizontal piece of line.if the graph shows acceleration against time, then constant  velocity is a piece of line that lies on the x-axis . . it's value is zero.
