Question 487086
you need to solve for y in order to graph the equation.
2y + x = 0
subtract x from both sides of the equation to get:
2y = -x
divide both sides of the equation by 2 to get:
y = -x/2
that's the equation you want to graph.
since it's a straight line, all you have to do is plot 2 points and then draw a straight line through them.
if you pick x = -2, and x = 2, your table of values would like this:
<pre>
       x       y = -x/2
      -2       1
       2      -2
</pre>
when x = -2, y = 1
when x = 2, y = -1
draw your straight line between those 2 points and extend it to the limits of the graph and you have your graph of that equation.
you graph should look like this:
{{{graph(400,400,-5,5,-5,5,-x/2)}}}
from this graph, you can see that when x = 2, y = -1, and when x = -2, y = 1.
