Question 4571
case i) suppose the given line has slope m and has y-intercept c , then the equation of line can be written as 
      y=mx+c

case ii) suppose the line making intercept with a and b on x and y axis respectively ..means intercept with x-axis at (a,0) and with y-axis (0,b), then
the equation of the line can be written as
        {{{x/a + y/b = 1}}}
