y2-y1/x2-x1
Y(subscript 2) - Y(subscript 1) / X(subscript 2) - X(subscript 1)
The formula for slope is the difference in y-values divided by the difference in x-values. the slope of a line is its steepness or its rate of change. There are 4 types of slopes positive, negative, zero, and undefined.
Try adding a picture next time maybe...?
