Mass = density* volume
since density= mass/volume then mass/volume*volume=mass
= 4.5*0.4 = 1.80g
She is starting at 4000, so that is the y-intercept of the graph. She is descending at 40 feet per minute, so her rate of change or slope is -40. The graph would look like this:
2) longest line is (-1, -3) and (-1, 7)
3) (-1, -3), (-6,2), and (2,4)
Reflection over the y axis Then a translation of 2 units down
