Question

Consider following equation m=y2-y1/x2-x1 find slope

Answer 1

This expression is the one used to find slope. It represents the change in y-values divided by the change in x-values, which we get from coordinates.

For example, if you are given the points (-3, 7) and (2, 3) and asked to find the slope, you would use the form y2 - y1 / x2 - x1 like so:

7 - 3 / -3 - 2
4 / -5
-4/5

And the slope of the line of my example is -4/5.

Answer 2

This the definition for slope. M=slope.
Slope = rise/run or delta(y)/delta(x) which simply stands for change in y divided by change in x which is m(slope)=y2-y1/x2-x1
