To determine if the given equation is a linear equation, let's first see if we can rewrite it in standard form.
Ax+ By= CIn this form, A, B, and C are constants and either A or B must be nonzero.
This is the standard form of the given equation. Below we have highlighted how it corresponds to the general standard form.
-7x+7y=0⇔ -7x+ 7y= 0
When written this way, we can see that A= -7, B= 7, and C= 0. Since this equation can be written in standard form, it is linear.
