The equations of three lines are given below.
Line 1: 3y = -2x + 7
Line 2: y=-x+7
Line 3: 6x - 4y= -4

Line 1 and Line 2:
Parallel Operpendicular
Neither
Line 1 and Line 3:
Parallel
Perpendicular
Neither
Line 2 and Line 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?
