And the slope of the line. The basic formula for a linear equation is y mx b where m is the slope. Sub SLOPEcal start the slope function scope.
What is important is that you subtract your y-values and x-values in the same order and that you remain consistent.
Using the Slope Formula Definition of Slope. Note the X and Y value for each of the points. Designate the X and Y value for points 1 and 2. Use subscripts to identify them in the slope formula.
