12. Plotting a single point Transcript Consider the following graph, which shows the relationship between an individual’s income and the number of times he or she eats out each month. Your AnswerManuel01234567891020181614121086420QUANTITY (Dinners out per month)INCOME (Thousands of dollars per month)8, 16 Correct Answer Points: 1 / 1 Hint : When answering the following, be sure to specify the appropriate units. The blue point already shown on the graph shows the data for Poornima. According to the graph, Poornima’s income is \$5,000 per month , and she has 10 dinners out per month . Points: 1 / 1 Close Explanation
Suppose Poornima’s friend Manuel has an income of \$8,000 per month and has 16 dinners out per month. Use the orange point (square symbol) to plot the data for Manuel.
Because Manuel chooses to have 16 dinners out per month and the vertical axis of the graph shows the quantity of dinners out per month, you should have placed the orange point at a vertical coordinate of 16. 13. Points and slopes Transcript 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-axisX-axisBDCA 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". Scenario Relationship Line As the number of hours spent studying rises, the average grade received rises. Positive D As the number of hours spent studying falls, the likelihood of D
getting an A falls. As the number of hours spent watching TV rises, the average grade received falls.
