m = ( y2 - y1 ) / ( x2 - x1 )


(1)

x1 = 1 , x2 = 10

y1 = 7 , y2 = 1

m = ( y2 - y1 ) / ( x2 - x1 )

m = ( 1 - 7 ) / ( 10 - 1 )

m = - 6 / 9 = - 2 ∙ 3 / 3 ∙ 3 = - 2 / 3

Answer B


(2)

x1 = - 5 / 3 , x2 = - 2

y1 = - 1 , y2 = 9 / 2

m = ( y2 - y1 ) / ( x2 - x1 )

m = [ 9 / 2 - ( - 1 ) ] / [ - 2 - ( - 5 / 3 ]

m = ( 9 / 2 + 1 ) / ( - 2 + 5 / 3 )

m = ( 9 / 2 + 2 / 2 ) / ( - 6 / 3 + 5 / 3 )

m = ( 11 / 2 ) / ( - 1 / 3 )

m = 11 ∙ 3 / 2 ∙ ( - 1 )

m = 33 / - 2

m = - 33 / 2

Answer C
