Question

What is the general form of the equation of the line shown?

A)x + y = 0

B)x - y = 0

C)-x - y = 0

Answer 1

B) x - y = 0

Explanation:

The equation for the line shown is y=x. This can be written in general form by subtracting y:

x - y = 0

_____

General form for the equation of a line is ...

ax +by +c = 0

where a, b, c are preferred to be mutually prime integers and a ≥ 0. If a = 0, then b ≥ 0.
