$2 x = 4 y - 1$

Step 1

The slope-intercept form is $y = m x + b$ , where $m$ is the slope and $b$ is the y-intercept.

$y = m x + b$

Step 2

Rewrite in slope-intercept form.

Step 2.1

Rewrite the equation as $4 y - 1 = 2 x$ .

$4 y - 1 = 2 x$

Step 2.2

Add $1$ to both sides of the equation.

$4 y = 2 x + 1$
