Answer
Plot the points $(-1,-3),(0,-3.5),(1,-4)$ and graph the line.
Work Step by Step
We are given the equation:
$x=-2y-7$
Rewrite the equation in the standard form $y=ax+b$:
$x+7=-2y-7+7$
$x+7=-2y$
$y=-\dfrac{1}{2}x-\dfrac{7}{2}$
Determine 3 points belonging to the graph:
$x=-1\Rightarrow y=-\dfrac{1}{2}(-1)-\dfrac{7}{2}=-3$
$x=0\Rightarrow y=-\dfrac{1}{2}(0)-\dfrac{7}{2}=-3.5$
$x=1\Rightarrow y=-\dfrac{1}{2}(1)-\dfrac{7}{2}=-4$
Plot the points $(-1,-3),(0,-3.5),(1,-4)$ and join them to graph the line:
