Refer to the explanation.

Graph:

$y = - 2 x$ $y=-2x$ is a linear equation in slope-intercept form:

$y = m x + b,$ $y=mx+b,$

where:

$m$ $m$ is the slope and $b$ $b$ is the y-intercept.

Determine the x- and y-intercepts.

The x-intercept is the value of $x$ $x$ when $y = 0$ $y=0$ , and the y-intercept is the value of $y$ $y$ when $x = 0$ $x=0$ .

According to the slope-intercept equation, the y-intercept in the given equation is $0$ $0$ , and the point is $(0, 0)$ $(0,0)$ .

To determine the x-intercept, substitute $0$ $0$ for $y$ $y$ and solve for $x$ $x$ .

$0 = - 2 x$ $0=-2x$

Divide both sides by $- 2$ $-2$ .

$\frac{0}{- 2} = x$ $0/(-2)=x$

$0 = x$ $0=x$

The x-intercept is $0$ $0$ and the point is $(0, 0)$ $(0,0)$ .

The line will go through the origin.

Plot the x- and y-intercepts and draw a straight line through them.
