what is slope

The "angle", in some sense, from horizontal. For further information, please review some of the lessons available online.

Thank you.

The slope of a line is the ration of the change in y-coordinates to the corresponding change in the x-coordinates. The slope tells you how steep a line is.

The slope equals:
change in y-coordinates
_____________________
change in x-coordinates

which is the same as:

y2-y1
______
x2-x1

The slope of a line stays the same no matter what two points on the line are used.
 
I think it is important to know that "slope" is a concept, not an object. You cannot go down to the store and buy three slopes. It describes a linear relationship between two quantities.
