Question 228301
Find the slope of (-7,9) (8,3)


Step 1.  The slope of the line m is given as


{{{ m=(y2-y1)/(x2-x1)}}}


where for our example is x1=-7 y1=9, x2=8 and y2=3 (think of {{{slope=rise/run}}}).  You can choose the points the other way around but be consistent with the x and y coordinates.  You will get the same result.


Step 2.  Substituting the above values in the slope equation gives


{{{m=(3-9)/(8-(-7))}}}


{{{m=-6/15=-2/5}}}


Step 3.  The slope m is calculated as {{{-2/5}}}.


I hope the above steps were helpful.
