What is the slope of a line perpendicular to the y-axis? Select "Undefined", if applicable. The slope of the line is Undefined X 5(a) Write the equation in slopeintercept form, and determine the slope and yintercept. (b) Graph the equation using the slope and yintercept. 4x2y=8 Part: 0/ 2 Part 1 of2 (a) "he equation written in slopeintercept form is D. "he slope is D. lime/lied "he yintercept is D.(wnte your answer as an ordered pair.) X (a) Use slopeintercept form to write an equation of the line that passes through the two given points. (b) Write the equation using function notation wherey =f(x). (57 2) and (97 10) Part 1 of2 The equation of the line in slopeintercept form is . Part 2 of2 The equation of the line in function notation is D = D _ The number N (t) of new cases of a flu outbreak for a given city is given by N (t) = 5500 -2-0.05 , where t is the number of months since the outbreak began. (a) Find the average rate of change in the number of new flu cases between months 0 and 2, and interpret the result. (Round to the nearest whole unit.) (b) Find the average rate of change in the number of new flu cases between months 4 and 6, and between months 10 and 12. (Round to the nearest whole unit.) (c) Use a graphing utility to graph the function. Use the graph and the average rates of change found in parts (a) and (b) to discuss the pattern of the number of new flu cases. Part: 0 / 4 Part 1 of 4 (a) The average rate of change in the number of new flu cases between months 0 and 2 is approximately X 5 The number of new flu cases (Choose one) by approximately cases per month during this time interval. dropped increased
