Which of the following are point-slope equations of the line going through (3, 6) and (1, 2)? check all that apply. a. y - 2 =1/2 (x - 1) b. y - 6 =1/2 (x - 3) c. y - 2 = 2(x + 1) d. y - 6 =1/2(x + 3) e. y - 2 = 2(x - 1) f. y - 6 = 2(x - 3)

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?
