See graph
Explanation:
We can see that the equation represents a straight line. Also that
Two points are sufficient to draw a straight line.
However, it is advisable to have three points so that error, if any, while calculating two points on the lines can be cross checked.
-
For
#x=0# , we obtain#y=0# , so origin is a point on the line. -
For
#x=5# , we obtain#y=-10# , so next point is#(5,-10)# -
For
#x=-5# , we obtain#y=10# , another point is#(-5, 10)#
Plotting these points we get the graph
graph{2x+y=0 [-20, 20, -10, 10]}
