How do I determine the slope of the line passing through (-3,4) and (6,2).

The of slope of a line, G, is given by the formula change in y over change in x, i.e. G = change in y/ change x.

change in y = 2- 4

change in x = 6 - -3

G = (2-4)/ (6 - -3)

G = 2/ (6+3)

G = 2/9

Alternatively you can subtract the second pair of coordinates from the the first.

change in y = 4 - 2

change in x = -3 -6

G = (4- 2)/ (-3-6)

G = -2/-9

G = 2/9.

Hope this helps! You can ask any question if there is any issue.

I don't think that this is the correct answer because it says -2/9 on the answers section of the document.

Wait, I messed up the question.

May 18th, 2015

Yeah I have seen the mistake

change in y = 2- 4 = -2

change in x = 6 - -3 = 9

G = -2/9

Sorry for the delay and for the wrong answer.
