Answer:
Slope=-3
Y-intercept=(0,-6)
Explanation:
First of all, you want to rearrange this in slope-intercept form. slope intercept form is y=mx+b.
In this equation, the slope is m and the y-intercept is b.
So, rearrange the equation.
You end up with y=-3x-6
So, by comparing the original formula to this question, m=-3, while b=-6. But, when writing the y-intercept, you write it as a coordinate. Since coordinates are structured (x,y), you would write the y-intercept as (0,-6).
