(16) y = - 7x + 2

(17) y = 5x + 4

(18) y = - x + 9

(19) y = 1/5x

(20) y = - 2/3x + 1

(21) y = 4/3x - 5

(16) m=-7, b=2 where m is the slope and b is the y-intercept

(17) m=5, b=4 where m is the slope and b is the y-intercept

(18) m=-1, b=9 where m is the slope and b is the y-intercept

(19) m = 15, b=0 where m is the slope and b is the y-intercept

(20) m = - 23, b=1 where m is the slope and b is the y-intercept

(21) m = 43, b=-5 where m is the slope and b is the y-intercept
