Question 171047
Please help me solve this 
calculate the slope of the line passing through each pair of points. Then tell whether the line rises, falls, is horizontal, or is vertical? 
(3,5) and (9,15) slope=________,_________ 
--------------------
The slope, m, is the diff in y/diff in x.
m = (15-5)/(9-3)
m = 10/6 = 5/3
The slope is positive, so it "rises" from left to right (as x increases).
