graph{y=-4x [-10, 10, -5, 5]}

Explanation:

To solve this equation, first move the $4 x$ $4x$ to the other side to make the $y$ $y$ by itself. Do this by subtracting $4 x$ $4x$ from each side.

$y + 4 x - 4 x = 0 - 4 x$ $y+4x-4x=0-4x$

Simplify

$y = - 4 x$ $y=-4x$

Once you simplify, plug in random values for $x$ $x$ $(1, 2, 3, etc)$ $(1, 2, 3, "etc")$ and then the answer you get is your $y$ $y$ value. You can use the graph for help.

Example:

$x = 2 \Rightarrow y = - 4 (2) = - 8$ $x = 2 => y=-4(2) =-8$

So

$x = 2, y = - 8$ $x = 2, y = -8$

See explanation.

Explanation:

$4 x + y = 0$ $4x+y=0$
$y = - 4 x$ $y=-4x$

Since the equation has the form of $y = a x$ $y=ax$ , we conclude that the graph will be a straight line passing through the $(0, 0)$ $(0,0)$ point.

You then insert $2$ $2$ values for $x$ $x$ $(x_{1}, x_{2})$ $(x_1,x_2)$ and get $2$ $2$ values for $y$ $y$ $(y_{1}, y_{2})$ $(y_1,y_2)$ .

So you have $2$ $2$ coordinates: $(x_{1}, y_{1})$ $(x_1,y_1)$ and $(x_{2}, y_{2})$ $(x_2,y_2)$ .

You mark them as points and draw a straight line that passes through both points and the $(0, 0)$ $(0,0)$ point.
