If the linear equation y = 7x - 4 is written in standard form, the standard form being ax +by +c =0, then what is the value of a, b and c?
none of these
The standard form of a linear equation is ax + by + c = 0.
The given equation is y = 7x - 4.
It can be rewritten as -7x + y + 4 = 0.
Thus, a = -7, b = 1 and c = 4.
Thus, the correct option is A.
