$y = 4 - 2 x$
$y = 4$
$x$Intercept
$\left ( 2 , 0 \right )$
$y$Intercept
$\left ( 0 , 4 \right )$
$x = 0$
$ $ Solve a solution to $ x$
$\color{#FF6800}{ 4 } \color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = 4$
$ $ Organize the expression $ $
$\color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 4 } = 4$
$- 2 x \color{#FF6800}{ + } \color{#FF6800}{ 4 } = 4$
$ $ Move the constant to the right side and change the sign $ $
$- 2 x = \color{#FF6800}{ 0 }$
$\color{#FF6800}{ - } \color{#FF6800}{ 2 } \color{#FF6800}{ x } = \color{#FF6800}{ 0 }$
$ $ Change the sign of both sides of the equation $ $
$2 x = 0$
$\color{#FF6800}{ 2 } \color{#FF6800}{ x } = \color{#FF6800}{ 0 }$
$ $ Divide both sides by the same number $ $
$\color{#FF6800}{ x } = \color{#FF6800}{ 0 }$
