What is the range of A?\n22.     What kind of number will have a negative B?\n23.     Why do scientists use graphs?\n24.     What variables go on which of the axes of a graph?\n25.     How do direct and inverse relationships differ?\n26.     Describe the graph of a direct linear relationship.\n27.     Describe the graph of an inverse parabolic relationship.\n28.     What is the slope of a horizontal line?\n29.     In an experiment the independent variable does not change. What is the slope of the graph?\n30.     During a lab experiment the temperature of the gas in a balloon is varied and the volume is measured. \n Which of the two variables will be graphed on the horizontal axis and which will be graphed on the vertical axis?\n31.     What kind of relationship exists between P and z in this equation? P = mv/z2\n
