$y = 4 x - 3$
$y = 13$
$x$Intercept
$\left ( \dfrac { 3 } { 4 } , 0 \right )$
$y$Intercept
$\left ( 0 , - 3 \right )$
$4x-3 = 13$
$x = 4$
$ $ Solve a solution to $ x$
$4 x \color{#FF6800}{ - } \color{#FF6800}{ 3 } = 13$
$ $ Move the constant to the right side and change the sign $ $
$4 x = 13 \color{#FF6800}{ + } \color{#FF6800}{ 3 }$
$4 x = \color{#FF6800}{ 13 } \color{#FF6800}{ + } \color{#FF6800}{ 3 }$
$ $ Add $ 13 $ and $ 3$
$4 x = \color{#FF6800}{ 16 }$
$\color{#FF6800}{ 4 } \color{#FF6800}{ x } = \color{#FF6800}{ 16 }$
$ $ Divide both sides by the same number $ $
$\color{#FF6800}{ x } = \color{#FF6800}{ 4 }$
