# How do you graph y=-2x-4?

$- 2 x$ is the gradient (or steepness) of the line. The gradient tells us that for $1$ square to the right, how many squares we go up or down. With a negative number, we go downwards, and with a positive one we go up. this means that for every $1$ square we go to the right, we go down $- 2$.
$- 4$ is the y-intercept, which shows us at which point on the y-axis (vertical axis) the line crosses. Therefore, the line will cross the y-axis at $- 4$.
to draw the line, plot a point on he coordinate $\left(0 , - 4\right)$, then go $1$ box across and $2$ down, and plot a second point. Continue to do this until you no longer can. Then work the opposite direction, going $1$ to the left and $2$ up
