Question

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?


  1. -7,-1,-4 

  2. none of these

  3. -7,1,4

  4. 7,-1,4


Solution

The correct option is C

-7,1,4


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.
