Answer:

x + 3y = 15

Step-by-step explanation:

Line is passing through the points (3, \:4) = (x_1,\:y_1)\:and\: (9, 2)=(x_2,\:y_2)

Slope of line (m)= (2 - 4)/(9 - 3) = -2/6 = -1/3

Equation of line in point-slope form is given as:

y-y_1 =m(x-x_1)

Plugging the values of x_1,\: y_1\: and \: m in the above equation we find:

y-4 =-\frac{1}{3}(x-3)

\implies 3y-12 =-x+3

\implies x+ 3y =12+3

\implies \huge {\orange{\boxed{x+ 3y = 15}}}

This is the required equation of line in the form \red{\bold{ax + by = c}}

                  2x^3 - 2x - 4

3x + 1        6x^4 + 2x^3 - 6x^2 - 14x - 1
                  6x^4 + 2x^3
                
                                       -6x^2 - 14x - 1
                                       -6x^2 - 2x
     
                                                 -12x - 1

                                                           3

3x + 1 is not a factor of the dividend because, dividing the dividend with 3x + 1 gives a remainder.
