What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (−1, −1)? y + 1 = (x + 1)

First find the slope of this new line; it's the same as the slope of the "given line," which you unfortunately have not yet given.  Let's call that slope "m."

Then, the equation in point-slope form of the new line is

y - (-1) = m(x - [-1]), or    y+1 = m(x+1)

Please go back to the original question, obtain the slope of the "given line," and substitute that value for m in y+1 = m(x+1).
