-4r + 5y = 8
61 - y = 11

If f(x)=2x-6 and g(x)=3x+9, find (f-g)(x)

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?

The slope of the line whose equation is y - 3 = 0 is 0 3 no slope
