Create and solve systems of linear equations graphically and algebraicallyIdentify systems that are consistent, inconsistent, dependent, or independent and explain reasoning Student Directions Make three systems of two equations inequalities from any in the box. Use each method to solve one system. Show your work y = - 6x; y = 2x + 1; y = 5x - 11; y >= - 2x + 4; 2x + 2y = 2; y = 1/3 * x + 3; y = 3x + 1; y <= - x + 4; y = 2x - 1; x + y = 1; y >= 0 graphingb. substitutionc. elimination Then find a system that has cach of the following. d. coincident lines eintersecting lines f. parallel lines perpendicular lines Explain your reasoning. Your models should present situations in which you make comparisons and draw conclusions

Data from 2005 for various age groups show that for each $100 increase in the median weekly income for whites, the median weekly income of blacks increases by $105. also, for workers of ages 25 to 54 the median weekly income for whites was $676 and for blacks was $527. (a) let w represent the median weekly income for whites and b the median weekly income for blacks, and write the equation of the line that gives b as a linear function of w. b = (b) when the median weekly income for whites is $760, what does the equation in (a) predict for the median weekly income for blacks?
