$y = 2 x + 5$
$y = 9$
$x$Intercept
$\left ( - \dfrac { 5 } { 2 } , 0 \right )$
$y$Intercept
$\left ( 0 , 5 \right )$
$2x+5 = 9$
$x = 2$
$ $ Solve a solution to $ x$
$2 x \color{#FF6800}{ + } \color{#FF6800}{ 5 } = 9$
$ $ Move the constant to the right side and change the sign $ $
$2 x = 9 \color{#FF6800}{ - } \color{#FF6800}{ 5 }$
$2 x = \color{#FF6800}{ 9 } \color{#FF6800}{ - } \color{#FF6800}{ 5 }$
$ $ Subtract $ 5 $ from $ 9$
$2 x = \color{#FF6800}{ 4 }$
$\color{#FF6800}{ 2 } \color{#FF6800}{ x } = \color{#FF6800}{ 4 }$
$ $ Divide both sides by the same number $ $
$\color{#FF6800}{ x } = \color{#FF6800}{ 2 }$
