Question 735058
Call one point, point 1 and call the other point, point 2.  Formula for slope is {{{m=(y[2]-y[1])/(x[2]-x[1])}}}.


Slope-intercept form takes the arrangement, {{{y=mx+b}}}.  From this, a general formula for b is {{{b=y-mx}}}.  Pick either point 1 OR point 2 and substitute for x and y and compute b.  


Now you will have the value for m and for b to write the equation for your line.
