This is my homework assignment, and this isn't the real problem. I made this one up. so you could walk me through the steps so I can do the real problem!!
What is the slope of the line that passes through the pair of points (3/2 , -2) and (-3, 7/3).
slope = (difference in the y values)/(difference in the x values), make sure you subract in the "same direction"
slope = (-2 - 7/3)/(3/2 - (-3)
= (-6/3 - 7/3)/(3/2 + 6/2)
=(-13/3) / (9/2)
= (-13/3)(2/9) = -26/27
by subtracting in the same direction ....
we could have done:
slope = (7/3 - (-2)) / (-3 - 3/2)
and obtain exactly the same anwer
Thank you so much Reiny I finally understand (: it means a lot!
