$y = - 2$
$y = \dfrac { x + 3 } { 2 }$
$x$Intercept
$\left ( - 3 , 0 \right )$
$y$Intercept
$\left ( 0 , \dfrac { 3 } { 2 } \right )$
$-2 = \dfrac{ x+3 }{ 2 }$
$x = - 7$
 Solve a solution to $x$
$\color{#FF6800}{ - } \color{#FF6800}{ 2 } = \color{#FF6800}{ \dfrac { x + 3 } { 2 } }$
 Multiply both sides by the least common multiple for the denominators to eliminate the fraction 
$\color{#FF6800}{ - } \color{#FF6800}{ 4 } = \color{#FF6800}{ x } \color{#FF6800}{ + } \color{#FF6800}{ 3 }$
$- 4 = \color{#FF6800}{ x } + 3$
 Move the variable to the left-hand side and change the symbol 
$- 4 \color{#FF6800}{ - } \color{#FF6800}{ x } = 3$
$\color{#FF6800}{ - } \color{#FF6800}{ 4 } - x = 3$
 Move the constant to the right side and change the sign 
$- x = 3 \color{#FF6800}{ + } \color{#FF6800}{ 4 }$
$- x = \color{#FF6800}{ 3 } \color{#FF6800}{ + } \color{#FF6800}{ 4 }$
 Add $3$ and $4$
$- x = \color{#FF6800}{ 7 }$
$\color{#FF6800}{ - } \color{#FF6800}{ x } = \color{#FF6800}{ 7 }$
 Change the sign of both sides of the equation 
$\color{#FF6800}{ x } = \color{#FF6800}{ - } \color{#FF6800}{ 7 }$
