Suppose that when the interest rate on loans is 16 percent, businesses find it unprofitable to invest in machinery and equipment. However, when the interest rate is 14 percent, $5 billion worth of investment is profitable. At 12 percent interest, a total of $10 billion of investment is profitable. Similarly, total investment increases by $5 billion for each successive 2-percentagepoint decline in the interest rate. Describe the relevant relationship between the interest rate and investment in a table, on a graph, and as an equation. Put the interest rate on the vertical axis and investment on the horizontal axis. In your equation use the form i = a + bI, where i is the interest rate, a is the vertical intercept, b is the slope of the line (which is negative),and I is the level of investment.
The relationships between some economic variables w, y, and z and another economic variable, x, are shown in the graph above. Notice that the horizontal axis is labeled “x” since they are all functions of x but the vertical axis is not labeled. 1-1 Does the vertical axis need a label in order for you to be able to understand the graph?1-2What value of x minimizes w?
Sketch a graph to illustrate your idea of each of the following relationships. Be sure to label both axes appropriately. In each case, explain under what circumstances, if any, the curve could shift:
The relationship between a person’s age and height
Average monthly temperature over the course of a year
A person’s income and the number of hamburgers consumed per month
The amount of fertilizer added to an acre of land and the amount of corn grown on that land in one growing season
An automobile's horsepower and it's gasoline mileage (in miles per gallon)

- The variable shown on the vertical axis is _________ . The units for the variable on the horizontal axis are __________ . There are two ways to view the information presented on the graph. First, the graph tells us the amount a person with a certain income is likely to spend on a car, and second, it tells us the probable income of a person who spent a certain amount on a car. For example, if an individual earned $40,000 last year and purchased a new car, you would expect that person to have paid about _________ for the car. Similarly, if someone just paid $25,000 for a car, you could use this graph to estimate that this person's income was probably around __________ .arrow_forwardThe following graph contains four lines (A, B, C and D), each of which has a slope that is either positive, negative, zero, or infinite. For each of the following scenarios, indicate whether the relationship between the two variables is positive or negative, as well as which line on the previous graph has a slope that reflects this type of relationship. Hint: The X-axis and Y-axis on the graph are not labeled intentionally. You need to substitute the variables from each scenario for the horizontal and vertical axis. For example, in the first scenario, X-axis should be labeled “ The average grade received" and Y-axis should be labeled "The number of hours spent studying".
