$y = 2 x$
$y = - 7 x - 3$
$x$Intercept
$\left ( 0 , 0 \right )$
$y$Intercept
$\left ( 0 , 0 \right )$
$x$Intercept
$\left ( - \dfrac { 3 } { 7 } , 0 \right )$
$y$Intercept
$\left ( 0 , - 3 \right )$
$2x = -7x-3$
$x = - \dfrac { 1 } { 3 }$
$ $ Solve a solution to $ x$
$2 x = \color{#FF6800}{ - } \color{#FF6800}{ 7 } \color{#FF6800}{ x } - 3$
$ $ Move the variable to the left-hand side and change the symbol $ $
$2 x + 7 x = - 3$
$\color{#FF6800}{ 2 } \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 7 } \color{#FF6800}{ x } = - 3$
$ $ Organize the expression $ $
$\color{#FF6800}{ 9 } \color{#FF6800}{ x } = - 3$
$\color{#FF6800}{ 9 } \color{#FF6800}{ x } = \color{#FF6800}{ - } \color{#FF6800}{ 3 }$
$ $ Divide both sides by the same number $ $
$\color{#FF6800}{ x } = \color{#FF6800}{ - } \color{#FF6800}{ \dfrac { 1 } { 3 } }$
