The given equation is x=−2y
⇒y=−12x
Here x is the independent variable.
We assign any 4 values of x and obtain the corresponding values of y.
x=−6
⇒y=3,
x=−2
⇒y=−1,
x=2
⇒y=−1
x=6
⇒y=−3
So, the ordered paires of values of (x,y)=(−6,3),(−2,−1),(2,−1) and (6,−3).
Now we plot them on a graph.
The line passesd through (0,0) and m=−12.
