3x-y+1=0

Explanation:

The standard form of a linear equation in two variables representing a line is ax+by+c=0.

Equation of a line passing through two points (x_1,y_1) and (x_2,y_2) is given by

(x-x_1)/(x_2-x_1)=(y-y_1)/(y_2-y_1)

Hence, equation of line passing through (1,4) and (0,1) will be

(x-1)/(0-1)=(y-4)/(1-4)

or (x-1)/-1=(y-4)/-3

or -3*(x-1)=-1*(y-4)

or -3x+3=-y+4

or 0=3x-y+4-3

or 3x-y+1=0
