1. If you knew that the vertical intercept for a straight line was 15, that the slope was -.5, and that the independent variable had a value of 8, the value of the dependent variable would be: 11 2. In a demand graph showing the relationship between price and how much of a good the buyers will buy, the convention that economists follow is to place price on the: Vertical axis even though it is the independent variable 3. On a graph of two variables, X and Y, ceteris paribus means that: Other variables not shown are held constant 4. There are two sets of (x,y) points on a straight line in a two-variable graph with y on the vertical axis and x on the horizontal axis. If one set of points was (0,6) and the other set (6,18), the linear equation for the line would be: y=6+2x 5. The slope of a straight line is the ratio of the: vertical to horizontal 6. If a linear relation is described by the equation was C = 35 - 5D, then the slope of the line would be: 7. If two variables are directly related they will always graph as: an upsloping line 8. When variables A and B are negatively correlated, it implies that: A and B may or may not be causally related 9. A relationship illustrated by an upsloping graph means that an: Decrease in the value of one variable causes the value of the other to decrease 10. There are two sets of (x,y) points on a straight line in a two-variable graph with y on the vertical axis and x on the horizontal axis. If one set of points was (0,75) and the other set of points was (75,25), the linear equation for the line would be: y=75-.66x 11. If you knew that the vertical intercept for a straight line was 150 and that the slope of the line was 4, then the dependent variable would be 250 when the value of the independent variable is: 25 12. If an inverse relationship exists between two variables, then: one variable increases as the other decreases 13. When illustrating graphically the relationship between the price of a stock and the quantity of a stock purchased, it is usually the case that: Other variables are assumed to be constant
