Find an equation of the line containing the given pair of points (3,5)& (9,8)

Ok, if we know 2 points we can determine the slope as the difference of the y-values over the difference of the x-values. Thus if P=(3,5)& Q=(9,8)
m =(8-5)/(9-3)
Now if you know the slope and a point you can write the equation as:
y-y0=m(x-x0), or
y=mx +(-mx0+y0) which is the point-slope form for the line and (x0,y0) is either of the two points above.
Do you think you can finish the equation?
