Exercise 18 Page 159

Can the equation be written in standard form?

Linear? Yes.
Equation: 5x-y=0

Practice makes perfect

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 A and B cannot both be zero.

y=4x+x

Add terms

y=5x

LHS-y=RHS-y

0=5x-y

Rearrange equation

5x-y=0

This is the standard form of the given equation. Below we have highlighted how it corresponds to the general standard form. 5x-y=0 ⇔ 5x+( -1)y= 0 When written this way, we can see that A= 5, B= -1, and C= 0. Since this equation can be written in standard form, it is linear.
