4. Use the values in your T-chart to graph the temperature on a hot summer day with respect to average household income. . Define the variables in this application and label the horizontal and vertical axes accordingly. . Label the scale for each axis. . Label the points on the graph that represent South Sacramento and Land Park. (a) In your graph, you drew [Circle one] a line or a line segment (b) Make sense of the intercepts of the line through these points in this context. Complete the statements. . The vertical intercept of the line would occur at and, in this context, it would mean.... . The horizontal intercept of the line would occur at and, in this context, it would mean.... (c) Find the slope of the line (since this is an application, be sure to include units). (d) How much does the temperature change for every $25,000 increase in average household income? Explain how your found your answer. 4 (e) Find the equation for line you graphed above
