B= 2000 + CD 98000 = B + CD substitute b in 98000 = 2000 + CD + CD add variables 98000 = 2000 + 2CD subtract 2000 from each side 96000 = 2CD divide each side by 2 48000 = CD
The slope of line q is that of line p scaled by a factor of 3 (not -3). The y-intercept of line q is 6 less than the y-intercept of line p. The appropriate choice is D. y = 3ax +b -6
