i got d is that right?

OpenStudy (aaliyahfairgood):

just a second

OpenStudy (danjs):

You have to first find the slope of theline through those 2 given points

OpenStudy (danjs):

slope = (-6 + 10) / (-7 + 9)

OpenStudy (danjs):

slope = 4/2 = 2

OpenStudy (danjs):

the slope of the given line is 2 the slope of a perpendicular line will be (- 1/2) y = (-1/2)x + b

OpenStudy (danjs):

only one choice has the correct slope of -1/2
