In order to find the slope of a tangent line at any given point, we must make use of the equation for the slope of the line. Thus, we must note for the equations of finding the slope since there are two equations that are commonly used based on the number of points given.
Formula for the slope of the line given two points:
m = (y2 - y1)/(x2 - x1)
y2, y1, x2, and x1 must be known.
Formula for the slope of the line given one point:
m = rise over run
m = y / x
