Answer:

Explanation:
We are given the slope of the line and a point on the line.
So, we can utilize the point-slope form, given by:

Where m is the slope and (x₁, y₁) is a point.
We know that the slope is 0. So, m = 0.
And we will let (-3, 3) be (x₁, y₁). Hence, by subsitution:

Simplify:

We can add 3 to both sides. Hence, our equation is:

As you would've expect, since it had a slope of 0, it is a horizontal line.
