Given points C (4,3) and D (-2,-5) find the slope of every line parallel to CD

OpenStudy (anonymous):

Well lines that are parallel have the same slope, so just find the slope of this line and that will be the slope of every line parallel to it.

Is the answer -9/-1

OpenStudy (anonymous):

You should get 8/6 or 4/3 for the slope

OpenStudy (anonymous):

(-5-3)/(-2-3)

OpenStudy (anonymous):

Its 2,-5 not -2,-5

OpenStudy (anonymous):

Let me get this right, the points are (4, 3) (2, -5)?

OpenStudy (anonymous):

In that case the slope would be 4

OpenStudy (anonymous):

how did I get -9/-1

OpenStudy (anonymous):

You subtracted wrong. it was (-5-3)/(2-4) which equals 8/2 which simplifies to 4
