How would you get the slope for these points, (1/8,5/3) and (-4/9,1/2). I know how to get a slope with two whole numbers, but for some reason I don't get the answer when the points are both fractions. I know the right answer, so if you could just show me the process taken to get there. Thanks!
 
The process doesn't change if the numbers are fractions. Just subtract as usual. Or are you saying that you don't know how to add and subtract fractions? If so, then try online lessons to brush up.

I know how to add and subtract fractions. The answer to the problem is 84/41. The formula for slope is y2-y1/x2-x1. So if i put the fractions in for those, 1/2-5/3= -5/6 , so i get one fraction over the other, and
-4/8-1/8= -5/8
don't know how to get to 84/41.
 
When dividing by a fraction, flip and multiply. For instance:

. . . . .(1/4) ÷ (2/5) = (1/4) × (5/2) = 5/8
