Answer
Refer to the image below for the graph.
Work Step by Step
Write the equation in $y=mx+b$ form by solving for $y$ to obtain:
$\dfrac{x}{2} - \dfrac{y}{7}=1
\\14\left(\dfrac{x}{2} - \dfrac{y}{7}\right) = 14(1)
\\7x-2y=14
\\-2y = -7x+14$
Divide both sides of the equation by $-2$ to obtain:
$\dfrac{-2y}{-2}=\dfrac{-7x+14}{-2}
\\y = 3.5x-7$
To graph the given equation, perform the following steps:
(1) Create a table of values by assigning values to $x$ then solving for the corresponding value of $y$ for each one.
(refer to the attached image below)
(2) Plot each point from the table of values, then connect the points using a line to complete the graph.
