Answer
As we can see from the equation, the slope is $-4$ and the y-intercept is $6$.
Work Step by Step
The equation is given in the slope-intercept form, which is given by the equation:
$$y = mx + b$$
where $m$ is the slope and $b$ is the y-intercept.
Let us rearrange the equation so it is easier for us to see the slope and y-intercept.
$$y = -4x + 6$$
As we can see from the equation, the slope is $-4$ and the y-intercept is $6$.
