Exercise 1 Page 169

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. 4x+y=3 ⇔ 4x+ 1y= 3 When written this way, we can see that A= 4, B= 1, and C= 3. Since this equation can be written in standard form, it is linear.
