1 You drop containers of eggs from several heights then count the number of broken eggs. dependent variable number of eggs independent variable heights 2 You exert forces at 10 pound increments on as toy car and measure the resulting speed. dependent variable speed independent variable force 3 You drop a physics teacher from a tall building and measure his speed at 1 second increments dependent variable speed independent variable time 4 You increase pressure at a rate of 10lbs/in2 and measure the resulting volume of a giant marshmallow. dependent variable volume independent variable pressure 5 Identify the axis on which the following variables are graphed. dependent variable y-axis independent variable x-axis 6 A B C Which graph is described by the equation y=kx2 C 7 A B C Which graph shows a linear relationship? B 8 A B C Which graph will produce a constant when (x)(y)? A 9 A B C Which graph is described by the equation y=mx+b B 10 A B C When pressure on a volume of gas is increased, the volume decreases. Which graph? A 11 A B C The human population is growing at an ever increasing rate. Which graph?
