A translation moves point V(–2, 3) to V prime (negative 2, 7). Which are true statements about the translation? The point moves two units left and four units up. The transformation rule is (x, y) right-arrow (x 0, y 4). The transformation is a vertical translation. The image is four units to the left of the pre-image. The translation can be described as (x, y) right-arrow (x minus 2, y 7).

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?
