Hi
I.Use the point-slope formula, {{{m =(y[2] - y[1])/(x[2] - x[1])}}} to find slope
II. then use Using the standard slope-intercept form for an equation of a line 
y = mx + b  where m is the slope and b the y-intercept to start the process
by substituting slope value found for m
III. use on the the ordered pairs to solve for b
IV. substitute that  value found for b in the equation 
For ex: Points (1,1)(5,6)  m = 5/4
 y = (5/4)x + b
 1 = (5/4) + b
 (-1/4) = b  therefore:  y = (4/5)x -1/4
