ANSWERS P. 170 & P.177-179P. 170

61.) point slope: y-2=3(x+2) 21.) y=-2x+8

Std. form: 3x-y=-8 22.) y=.5x+2

62.) Point slope: y-5=.5(x-5) 26.) yes one is vertical, one

Std. Form: x-2y= -5 is horizontal

63.) Point slope: y-6=2/3(x-2) 36.) no, no pairs of lines

Std. Form: 2x-3y=-14 have opposite reciprocal
