Answer:
4x - y = 1
Step-by-step explanation:
By substituting the coordinates of the points into the left side of the equations. Then if the value obtained is equal to the right side the equation is satisfied.
Using (0, - 1 )
4(0) - (- 1) = 0 + 1 = 1 = right side
Using (1, 3 )
4(1) - 3 = 4 - 3 = 1 = right side
Thus
4x - y = 1 is satisfied by both pair of numbers
