We then write the slope as a fraction. Formula for Slope of a Curve. When dealing with a curved line where the slope is changing you cant use the same formula.
I repeat we always measure slope going from left to right.
The formula for the slope of the straight line going through the points X 1 Y 1 and X 2 Y 2 is given by. It can be a positive or negative value. We then write the slope as a fraction.
