# What is the slope and y-intercept of the line  -y = - 4x ?

In the equation $- y = - 4 x$, the slope is $- 4$ and the y-intercept is zero.
The slope intercept form for a linear equation is $y = m x + b$, where $m$ is the slope and $b$ is the y-intercept.
In the equation $- y = - 4 x$, the slope is $- 4$ and the y-intercept is zero.
