The blue line on the following graph shows the speed of a bike as it accelerates down a hill. 20 18 16 14 12 SPEED (Feet per second) 10 Co 1 2 3 4 5 6 7 8 9 10 TIME (Seconds)The area of the shaded quadrilateral is W feet. The area of the quadrilateral corresponds to the W between The following diagram shows two triangles. 10 DISTANCE (Inches) 0 0 1 2 3 4 5 6 7 8 9 10 DISTANCE (Inches) The green (upper) triangle has an area of W . The purple (lower) triangle has an area of Place the orange triangle (square symbols) directly next to the green triangle so that the two triangles together make a rectangle. The total area this rectangle is W, which is W the area of the green triangle. The following table shows data on the relationship between a worker's years of education and the salary he or she is likely to earn. Education Salary (Years) (Thousands of dollars per year) 4 15 8 25 12 35 Use the orange points (square symbol) to plot the data from the table on the graph below. Line segments will automatically connect the points. SALARY (Thousands of dollars per year) 50 45 40 35 30 25 20 15 10 EDUCATION (Years) Salary L Brian @ Suppose Brian has 10 years of education. Use the black point (X symbol) to plot the point on the graph that most likely corresponds to Brian's data. Based on the graph you drew, Brian would likely earn a salary of around W per year. Ypsilanti Market Research conducted a survey to find out whether people who earn more money purchase more expensive goods. The following grapl indicates the relationship between income the survey subjects earned and the price of the home that they purchased. 500 450 400 350 300 250 200 150 100 PRICE (Thousands of dollars per horme) 50 INCOME (Thousands of dollars per year) The variable shown on the horizontal axis is The units for the variable on the vertical 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 home, and second, it tells us the probable income of a person who spent a certain amount on a home. For example, if an individual earned $50,000 last year and purchased a new home, you would expect that person to have paid about W for the home. Similarly, if someone just paid $250,000 for a home, you could use this graph to estimate that this person's income was probably around v The following graph contains four lines (A, B, C and D), each of which has a slope that is either positive, negative, zero, or infinite. @ Y-axis X-axis 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 orevious 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 nours spent studying\". Scenario Relationship Line As the number of hours spent studying falls, the likelihood of getting an A falls. v v As the number of hours spent watching TV rises, the average grade received falls. v v y > As the number of hours spent studying rises, the average grade received rises. True or False: Line A has a slope of infinity. O True O False The following graphs show the relationship between the price of apples and the quantity of apples supplied in two different regions, the North and the and South. Assume that the two lines are parallel. The following graphs show the relationship between the price of apples and the quantity of apples supplied in two different regions, the North and the and South. Assume that the two lines are parallel. PRICE (Dollars per pound) North South APPLES (Thousands of pounds per year)In the North, if the price goes up by $0.20 per pound, then the quantity supplied in the North goes up by 100 pounds per year. If the price of apples goes up by $0.20 in the South, what will happen to the quantity supplied? O The quantity will increase by 100 pounds per year. There is not enough information given to determine the supply change in the South. O O The quantity will decrease by 100 pounds per year. O The quantity will increase by 50 pounds per year
