Slope -4 passing through the point (5,3).
bonufazy [111]
A negative slope means the line would be going downward, so you would go down first (instead of up as with a positive slope), then over right.

Therefore, you would go down 4 (or negative 4 considering you are going down) and right 1.

Rise over run still applies here. Rise over run is a fancy way of saying to put the number (or slope) in fraction form.

-4 as a fraction would be -4/1.

So start at (5,3), go down 4 and over 1, repeatedly and you got it.

**Just remember the rise over run can be confusing with negative slopes.**

Find what percent 591 is of 2364
kati45 [8]
To find the percent you would divide 591 by 2364 
591/2364=.25
.25*100 = 25% 
Does that make sense?
