Final answer:
The standard form of the equation y=4x−1 is 4x−y+1=0.
Step-by-step explanation:
The standard form of the equation y=4x−1 is option d) 4x−y+1=0.
In standard form, the equation of a line is written as Ax + By = C, where A, B, and C are constants. To convert the given equation to standard form, rearrange the terms to get 4x - y + 1 = 0. Now the equation is in the standard form.
