Question

Write the equation y = 2 - 4x in standard form.

Can someone please explain to me how to do this problem? I'd appreciate it.

Answer 1

Standard Form of a Linear Equation
The "Standard Form" for writing down a Linear Equation is

Ax + By = C

A shouldn't be negative, A and B shouldn't both be zero, and A, B and C should be integers.

Example: Put this in Standard Form:
y = 3x + 2
Bring 3x to the left:
-3x + y = 2
Multiply all by -1:
3x - y = -2
Note: A=3, B=-1, C=-2
