Answer
points in the graph $$\left(0,0\right),(-2,4),\left(-1,2\right),(1,-2),(2,-4)$$
Work Step by Step
$$y = -2x$$
We can graph the equation by setting arbitrary values for $x$.
If $x=0$
$$y = -2x$$ $$y = -2(0)$$ $$y=0$$
We then have point $(0,0)$.
If $x=-2$
$$y = -2x$$ $$y = -2(-2)$$ $$y=4$$
We then have point $(-2,4)$.
If $x=-1$
$$$y = -2x$$ $$y = -2(-1)$$ $$y=2$$
We then have point $(-1,2)$.
If $x=1$
$$$y = -2x$$ $$y = -2(1)$$ $$y=-2$$
We then have point $(1,-2)$.
If $x=2$
$$$y = -2x$$ $$y = -2(2)$$ $$y=-4$$
We then have point $(2,-4)$.
