Hassan plotted point m in the coordinate plane below. on a coordinate plane, point m is 0.5 units to the left and 0.25 units down. he says that the plotted point is (0.5, 0.25). what is hassan’s error? the x- and y-coordinates are switched. both coordinates should be negative. the x-coordinate should be -2. the y-coordinate should be -1.

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?
