Hello,
Slope is rise/run, or y/x, and if you are given two pairs of points, this is the equation needed: (y2-y1) over (x2-x1).
Let me plug in the numbers: (4-(-2) over 5-(-3). And that is 6/8, which then is simplified to 3/4. So the slope of those two given points is 3/4. We do not divide or simplify it into a decimal because slope is a fraction, so we leave 3/4 as it is.
Hope this helps, and that my explanation is not too confusing!
