When a linear equation is written in slope intercept form the slope of the line can easily be. SLOPE function in Excel is categorized as statistical functions in Excel. First look at a graph of a line and find two points 1 and 2.
In a straight line equation which is formed by using Slope and Intercept where Slope is ratio of rise and run which are there anywhere in the straight line.
To find the slope you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points. If the slope is positivedo not change your answer. If the slope is negative just add a negative sign in front of your answer. Use subscripts to identify them in the slope formula.
