Determine if Linear 5x-y=4

$5 x - y = 4$

Solve the equation for $y$ .

Subtract $5 x$ from both sides of the equation.

$- y = 4 - 5 x$

Divide each term in $- y = 4 - 5 x$ by $- 1$ and simplify.

Divide each term in $- y = 4 - 5 x$ by $- 1$ .

$\frac{- y}{- 1} = \frac{4}{- 1} + \frac{- 5 x}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{y}{1} = \frac{4}{- 1} + \frac{- 5 x}{- 1}$

Divide $y$ by $1$ .

$y = \frac{4}{- 1} + \frac{- 5 x}{- 1}$

Simplify the right side.

Simplify each term.

Divide $4$ by $- 1$ .

$y = - 4 + \frac{- 5 x}{- 1}$

Move the negative one from the denominator of $\frac{- 5 x}{- 1}$ .

$y = - 4 - 1 \cdot (- 5 x)$

Rewrite $- 1 \cdot (- 5 x)$ as $- (- 5 x)$ .

$y = - 4 - (- 5 x)$

Multiply $- 5$ by $- 1$ .

$y = - 4 + 5 x$

A linear equation is an equation of a straight line, which means that the degree of a linear equation must be $0$ or $1$ for each of its variables. In this case, the degree of variable $y$ is $1$ and the degree of variable $x$ is $1$ .
