ALL WORK MUST BE SHOWN TO RECEIVE FULL CREDIT. Graphs MUST be on graph paper. 1. (6 pts.) Find the equation of the line through the points (0,7) and (3.-8). Put your answer in point-slope form and then use algebra to write it in slope- intercept form. 2. (6 pts.) Graph the line 4x + 3y = 24 using the intercept method. 3. (6 pts.) Graph the inequality 2x -y > 4 4. (6 pts.) Use algebra to find all values of x for which the given product will at least break even: C = 100x + 6000, R = 500x 5. (6 pts.) Solve the system of equations using: (a) the Graphing method, (b) the Substitution method and (c) the Elimination (or Addition) method, labeling each 3x +2y = -4 4x - 2y = -10 6. (6 pts.) Graph the feasible region for the system of inequalities. -2 sxs2 y21 X-y20 7. (6 pts.) Write the system of inequalities that describes the given conditions. A statistical consultant creates two kinds of reports: summary reports and inference reports. Each summary report requires 2 hours of analysis time and 1.5 hours to write the report. Each inference report needs 4 hours of analysis time and 2 hours of writing time. Suppose the consultant has only 15 hours available for analysis and 9 hours for writing. Clearly define your variables before using them in an inequality. A chart may help organize the information.
