Which equation correctly shows how to determine the distance between the points (9, -2) and (6,3) on a coordinate grid?
đ- (63)3 + (9-(-2)2
Od-(6+3)2 + (9+(-2))2
Od= V(6-9)2 +(3-(-2))2
Od=(6+9)2+(3+(-2))2

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?
